So, what is everybody doing for s14 gas tanks these days?

[DRIFTER-M]

FRsport and Enjuku seem to be out.

What is everyone doing? Used seems like a sucky alternative, being old and plastic doesn't seem much more than a band-aid. We all fuel cell from here on out? Just curious as I feel this will be a huge problem for s14 owners down the road, interesting to see the current idea to fix. I don't need right now, but it's something I constantly think about with the s14 and I suppose next time will be a fuel cell.

[Kingtal0n]

I wonder if S15 will fit

I already know they have the same 'lid'

There has to be a car with a similar shape tank out there somewhere. Somebody needs to just measure 999 of them to find it.

BTW where do they tend to crack? I have a 96 that isn't cracked yet and wondering when/where... too lazy to look it up... /spooonf

[Ryosuke Takahashi]

I'm actually researching how to go about doing a fuel cell in one of my s14s. Not really to sure how to go about it yet. Stepping outside to your car finding leaky gas all over the place is not fun. If I noticed anything it seems like the darker colored factory colors will crack sooner than let's say Aspen white. My emerald blue s14 always gets really hot throughout the day and it seems like that might have something to do with it. Where as the white one doesn't retain heat and is still holding up fine. Mine cracked on the passenger side bottom buldge that's over subframe and a pinhole size where the lid is where the lines and connectors meet.

[sXe240]

I am still learning about my s14 and I didn't even know about this issue. Luckily I checked and mine looks okay for now. Maybe contact an importer and see if they have any gas tanks in Japan you could get shipped here.

[Hoffman5982]

Can you not get them directly from the dealership? That's where I got mine

[Agamemnon]

I wonder if S15 will fit
S14 and S15 shared the same part# for the tank. Currently discontinued.

My advice is to search for a professional plastic repair shop focusing in hazardous materials storage. My crack formed on the passenger side just above the seam.

Well this is interesting.

This gives me the excuse I need to import an S15 for "parts".

yeah, man, parts... :rant2: $9000 for a naturally aspirated S15 with no drivetrain so I can get a $5 fuel tank
seriously though there are at least 5 importers within 100 miles of me that regularly bring back all manner of half-cut silvia stuff for the last 20 years. One of them must have an S15 tank they would part with. If they do not destroy them somehow that is. to be continued...

[DRIFTER-M]

You can certainly find used ones, but the general way plastic rot is I am not sure that is more than a bad-aid for a short time.

I thought about pulling mine and rhino coating it. Or a fuel cell, but man - idk if I want to do that drastic of a change especially for a car I still cruise in every so often.

Hoffman - dealerships seems to be out (or at least the majority) as it is now officially discontinued for I believe 2 years?

[simmode1]

Ahhh the main reason I got rid of my Zenki... aside from the shitty sunroof trim moulding.

IIRC, the issue seemed to only affect Zenki and not koukis from the last time I broached this topic.

Have fun with this one, guys.

[afishysilvia]

I’m around 250,000 miles on chassis with no issues at all (95 Zenki). Why not just go with fuel cell?

[Ryosuke Takahashi]

You cant legally smog the car in cali once you go fuel cell.

[afishysilvia]

I was not aware of this, for the S13 people you can register as classic. Zenki's will soon be able to 2020/2021 and obviously Kouki's after that.

[FaLKoN240]

I just picked up tank #3 yesterday. I have a 98...

[Agamemnon]

All the tanks are the same spanning all years.
Laurels,R33/34, etc all share the same tank. Who knows with Nissan replicating old parts for Skylines maybe will see an updated tank for us S-chassis folks.

do you have any further info on this? I have never heard of a classic car exemption for CA (just the 75 or older). I did manage to find this which states if your vehicle is older than 25 years old, it becomes smog exempt. I don't think that's accurate.


https://www.carsdirect.com/dmv/do-classic-cars-qualify-for-a-smog-exemption-in-California


I couldn't find anything on the dmv site other than this:

(it states that your car has to be 35 years or older to skip out on some portions of a smog check.)

[afishysilvia]

https://www.dmv.com/ca/california/custom-vehicle-registration

While this is vague and not even from actual DMV/CA, the document you provided is from 2012. I have seen this someone else but not sure on the DMV of CA's actual site. I myself have been looking for this too. I will be registered out of state soon so this wont be an issue. Back onto topic however, in regards to the fuel cell. Is this banned due to venting/re-circulation of gases? What if one provides original canister and has the proper routing of an original system?

[sXe240]

I don't know about in California but here in Nj my Zenki already qualifies for that. No inspection needed just have to register it and insure it that's all.

[loser101]

Should start a gofundme fund to make injection molds of the gas tank.

[feito]

Wasn't someone recently having a hard time giving a good one away? A real shame if that went to the trash. Anyway, only thing I can think of is a custom made metal one. Shouldn't be that hard for someone with experience. As long as it's seated properly, the rest should be easy.

[Ryosuke Takahashi]

Maybe this fuel tank problem is a blessing indisguise. If a fuel cell was installed in the trunk. Wouldnt that extra space where the OEM one sat create more clearance to further raise the subframe?

Typically would crack just above the banding strap for the tank.

I’ve seen the theory, but like FaLKon240 below, I have known kouki people it affected too - so I don’t think the theory of it being a Zenki issue only is completely true. There is another theory that the crack is caused by bad subframe bushings causing the subframe to bounce / put pressure on the tank. Maybe there is some validity to that? Would be interesting to see if someone with solid or poly bushings experienced the problem after replacing the bushings.

The real issue IMO is that Nissan used plastic. It was stupid.

I’m around 250,000 miles on chassis with no issues at all (95 Zenki). Why not just go with fuel cell?

Fuel cells are not cheap (at least for safer and reputable ones), not super easy to hook up, and simply unsafe for a Daily or a street cruiser. A rear end collision could be disastrous, You def have to fabricate a firewall and cage/ tube the trunk area to guarantee the safest fitting. You also lose trunk space, lose capacity in many cases, and lose simple stuff like fuel gauge readings.

I just picked up tank #3 yesterday. I have a 98...

Sigh. Friggin Nissan.

Nissan today cares very little (re: not at all) about us. I can’t see that happening :-/

To answer both of you - I once floated this on a local board a few years back. I thought it would be simple, doesn’t sound hard right? A dude that I know has extensive knowledge of fabrication and meta engineering chimed in and apparently it’s actually a seriously difficult process and would be insanely costly. I don’t remember the reasons, but gas tanks are apparently much more complex than one initially thinks. I thought of a go fund me up until his super detailed response, and I realized it was incredibly unlikely it would ever happen.

Maybe this fuel tank problem is a blessing indisguise. If a fuel cell was installed in the trunk. Wouldnt that extra space where the OEM one sat create more clearance to further raise the subframe?

Definitely a positive aspect. I just feel like there are several negatives as well, and not sure it justifies it fully.

A good fix (when it works), but definitely a band-aid. Still thinking cell is the best “permanent” route, but ugh. I really am thinking about doing the pesky subframe pull just to get mine coated in rhino shield while it is still mint, and see if that ends up making a difference in the long run.

[Kingtal0n]

There is another theory that the crack is caused by bad subframe bushings causing the subframe to bounce / put pressure on the tank. Maybe there is some validity to that? Would be interesting to see if someone with solid or poly bushings experienced the problem after replacing the bushings.


very interesting idea. I wonder if there is a correlation between manual transmission cars + cracked fuel tanks, given the prevalence of bad subframe bushings and manual transmission vs automatic cars without that issue. The 96 I have is original auto, still auto, and doesn't have a cracked fuel tank yet...

so anyone with an auto car, acquired a cracked tank with the auto and good subframe bushings... all it would take is 1 person to come forward to more or less eliminate the theory.

[Ryosuke Takahashi]

When I pulled mine out the oem bushings were still fresh. No play or stress cracks. Very firm for a old car. Even all the subframe arms weren't oxidized and very easy to break loose without much effort. But I remember the hose under the engine bay for the fuel filter burst. And when I went to replace the fuel filter, I checked it out and it was very constipated. Barely any air pressure could get through. So I'm thinking maybe it caused some back pressure in the fuel system causing the actual tank to crack open. My car is also a 94 auto

isn't a 94 a convertible S13 with a metal fuel tank

[Ryosuke Takahashi]

No it's a 9/94 s14.

[Kingtal0n]

thanks. So that didn't take long. New theory: tank pressure causes crack to form? Sounds reasonable enough. The plot thickens...

All I know is tomorrow I am calling everyone I know and looking for some spare fuel tanks. This threads got me all kinds of worried.

[Ryosuke Takahashi]

Ya even after finding another spare tank and installing it in it still smelled like gas. There was no leaks but I was scratching my head for the longest time. Until I found out the seal on my gas filler cap was shit now as well. I got a replacement and the smell went away. So like my whole fuel delivery system took a huge shit on me.

gas filler cap, so what part is this? Is that something you can fix from the outside of the car, or? Easy to replace? Where do you get the new part?

I've got so much to learn about the fuel tank area, it makes me sick.

My original 95 auto developed a crack in the typical spot while it was still an auto with decent condition bushings.

I suspect it’s a manufacturing defect. Every leak I’ve heard of is in the same spot every time. I’d be willing to bet that the plastic gets very thin in the area.

[Ryosuke Takahashi]

You know when you go to the gas station and release pressure from the gas cap? Like the actual cap was defected from the back pressure some how.

As a matter of fact... I've had solid subframe bushings for i dunno... 5-8 years now. My S14 has 405,000 miles on it. Never had a cracked fuel tank. Dunno if that's a coincidence or if that's the reason.

Err someone mentioned something about clogged fuel filter and excess pressure in the tank. I'm been running a z32 tt fuel filter for the longest time. Dunno if that makes a difference or not either. Maybe less prone to clogging vs oem 240sx-sized fuel filter. I dunno, just throwing some ideas out there.

[ZenkiKid]

Ive looked into this in the past.

From what Ive gathered theres no real benefit from registering a classic car other than cheaper registration. It still needs to get smogged IIRC

[jumpman2334]

Anyway, only thing I can think of is a custom made metal one. Shouldn't be that hard for someone with experience. As long as it's seated properly, the rest should be easy.
LOL. you are funny. can it be made? yes, are you willing to pay in the quadruple digits for a metal gas tank? No.

[Kingtal0n]

LOL. you are funny. can it be made? yes, are you willing to pay in the quadruple digits for a metal gas tank? No.

Oh come now. there are all manner of aftermarket aluminum tanks available. Just a couple weeks ago I passed by a friends shop as he was putting one into the stock tank location of a 70's Impala with a 2015 5.3L DI engine in it. It took some bending of the factory straps and some creative hardware but it fit well enough.

I've also seen a local fabricator make a pair of aluminum fuel tanks for a boat easily enough.

If you have the tig, the tools, how hard can it be? I might even ask if I see him in the near future what he thinks. I just don't like to ask questions about making stuff that I don't intend to have made up asap, waste of time, but this isn't such a big deal IMO.

[jumpman2334]

here is what most impala tanks look like:

Here is what a s14 tank looks like:


http://i50.tinypic.com/1zxus05.jpg




you are comparing apples to oranges. the complex shape of the s14 gas tank cannot be simply replicated like a square impala tank can. don't you think if it were that easy someone would have already chimed in and made one? have you made one of these? if so, I would love to see pictures.

[afishysilvia]

Kingtal0n this shit gets you nowhere bro trust me. Let them do/think what they want lol. Once all the tanks run out someone will do figure out a new method.

[jumpman2334]

I'm not trying to argue, just stating that having a fabricator build a few tanks with a shape like that is going to be $$$. its not an easy shape to replicate and would require a talented metal worker.


it would be cool if someone here has a contact/hookup to an injection molding company. do a group buy and hopefully if there is enough interest, do more, or keep a stock of some.

[spooled240]

Making a copy out of fiberglass could be viable solution. I just searched on it briefly and it looks like a specific type of resin and coating will have to be used it to make it resistant to gasoline and ethanol.

[FRpilot]

Maybe commission a shop to make a custom fuel tank that will pass evap?

Maybe these guys or something similar?

This is basically what the person I referenced said. He said for the niche sales, it would be over a grand - and that would be if we could even find someone to properly replicate the complex design.

Yep... Fuel cell is probably the answer. Anybody here ever do the idea I have and rhino coat? My thought process would be if your tank is in perfect condition, the rhino coat will bind it and give it strength so something like a stress fracture hypothetically wouldn't occur.

[Kingtal0n]

Sometimes having somebody telling you that something is impossible or difficult is just a motivational speech. Find it in your heart to thank those individuals for without them, who knows what wouldn't be invented.

In the above example I agree that the shape is complicated and agree that it could be very expensive and not to get our hopes up for a low cost solution anytime soon, but personally if I had access to the material and a tig I could create something that would fit. And I also believe that somebody will find a better/affordable solution when necessity breeds creation in a higher method that maybe easier than welding.
Everybody is correct and its still fun to discuss and re-evaluate in idle time because this also may stew up new ideas.

[feito]

It's just a slightly odd shape. Shit, you people are acting like it's something out of this world... For someone experienced with metal bending and welding, and with a chassis, or at least the rear half cut to be used as a model, it shouldn't be that hard. Obviously it will have square edges and might be a little larger or smaller, but as long as the mounting points, the pump base and breathers are the same, it should be all good. Shit, if I had to I probably would give it a try, except I would make it out of steel since Im not good with aluminum.

All due respect, not sure if you comment was intended for me or not - but I never once said it could not be done. I looked into funding this before, and was given some answers that it wasn't cheap or easy for our fuel tanks. You mentioned here that sizing may not be perfect, and this is one of the issues - how the s14 tank is tucked, there isn't much room for error. Making a custom mold and then making the tank isn't a cheap endeavor either, much less if one has to scrap or change the final product.


As I said before, there was someone who I know is very knowledgeable regarding fabrication and cars, and this person on a now retired forum (or I would pull up their details and post here) explained that it really wasn't feasible. Doesn't at all mean it can't be done, just that it won't be an easy or cheap thing to do, and will likely cost more than the large majority of our niche community would be willing to spend.


Even that F body tank you put up is much more simple than the s14 tank. It's definitely IMO the biggest s-chassis design flaw among all the chassis from 12-15. Nissan screwed up on the design and materials big time.

[spooled240]

I say fuck copying the original design, just make what fits. I would be ok with even sacrificing a few gallons of fuel capacity if I could have an aluminum tank that never leaked.

no relation, the z32 fuel filter makes no fucking difference. and technically, the tank does not crack - it just weeps. pinholes appear at the seam-weld, simple as that.

have you dolts looked at a stock tank? its a very odd, saddle-bag shape designed to hug the underbelly of the chassis. making one out of metal is totally out of the picture. the only solution is fuel cell, period.


IIRC, the issue seemed to only affect Zenki and not koukis from the last time I broached this topic.

here we go again, the magic and mystery of the kouki. its the same fucking tank, no difference.


You cant legally smog the car in cali once you go fuel cell.

who told you this? i think you are wrong.

the only issue that is big here, is that the tank doesnt just hold fuel, it also holds the pressure unit needed for obd2 functionality. this is in the later tanks, its actually molded into the tank.

as these cars get older, the only solution will be fuel cell... or convert your car to electric.

ive already posted on this problem years ago, i was able to fix this issue by heating the tank (empty, of course) with a heat gun - and then basically melting nylon (from zip ties or somewhere else) and just plastic welding the two together. it works surprisingly well. however, my car is no longer compliant as i ditched the charcoal canister/evap system - the tank is no longer being pressurized as it originally was. i still have the flip valve, so it holds fumes... just not the same amount of pressure as originally designed.

[Kingtal0n]

Maybe S15 won't be 'thin'. I think that is the best way to handle this for those of us withing to keep 14s for long time as it eliminates probabilities for finding 'thin s14' versions. Even if it does cost 1k it becomes part of the cost of the car when you look to buy an S14 from now on, buyer wants $400 but its $1400 because everyone knows the fuel tank is bad. It suddenly becomes a car that only elitist can drive, everyone has a 240, few drive them, wham a new muscle car elite entry only is born

Until then however, I think i will find a leaking 14 tank. So I can practice fixing it and then have it on the side ready to go in case needed. Unless stumble on 15

I think this is the best 2 options for full capacity and best location (hidden well) for us now for a while. Otherwise throw a boat tank and go caution to the wind

Hmm what doesn't make sense
Your options are:
1. used s14 tanks
2. used s15 tanks
3. fab a tank

okay pick one. Whats that? used s14 tanks are going to all probably crack? Okay so fab one. What? It costs $1000 or some crazy fab work? Okay so then... what option is left over...

so fab one up already, since you're so quick to talk.

i know how to tig weld. i can tell you, the chances of fabbing up that tank out of metal are pretty much none. no one got time for that bullshit, especially broke ass 240 owners. cut the spare out of the trunk and install a fuel cell - done.

but no, you're going to suggest we fab it up like that toy 2 gallon motorcycle tank. sure.

that is a good find, but one thing you guys need to remember is that the tank has an integrated pressure sensor that is affixed (welded) to the tank, as well as the vent ports on the corners of the tank. at least thats what I believe those are. i never cut the tank apart to dissect and confirm.

we never have this problem over in England with our 'euro-spec' s14's
the s15 tank is the same but the hose connections on the 'lid' are different on an s15 as the fuel hose are plastic so it has push on and click style connectors. also the fuel pump plug on the 'lid' is different to an s14 one.so your s14 loom wont plug directly into it.

maybe see if cars that have lived in not so hot climates for longer periods of time suffer with bad tanks. it pretty much never gets over 30 degree Celsius over here.

I don't think there is any real difference between the tanks. I wouldn't be able to say what of my friends over the last 15 years have had it happen, I would probably surmise that your absence of problems is due to people not really talking about it much. I could however be incorrect, not trying to insinuate that you are a liar by any means.

It could be other things, our cars probably stack mileage up faster in the states, but there are plenty of cooler climate regions in the US and people still have these problems. The tanks are no different from US -> JP -> EU as far as I know.

FWIW, my s14 I am the second owner of and have owned for well over a decade and it hasn't been a problem even at 2xx,xxx miles. But I know that it is inevitable as, well, plastic sucks butt and will eventually rot. That is the nature of the beast. I started this thread due to I tend to forward plan things, and noticing the absolute scarcity of new tanks figured it was a discussion worth having now to help people circumvent the issue going forward.

I do agree with ixfxi though, I think the only real legitimate option is fuel cell, it just isn't a perfect option unfortunately. I am very curious to see if I rhino coat mine will it have any real affect on the durability. I plan to replace my bushings soon in the subframe, so I think as I tear down the car, I may drop the tank and have it coated for science.

Well... here’s a bump-

Pulled my s14 out of storage to bring home. Get off trailer, park it in the garage.

Next day when I open the garage - gas smell is strong. No visual leak, but I have a feeling if I go to pull it that I will find one.

So.

Anybody else want to chime in? I suppose there really aren’t many new options. One thing is for sure, I really don’t like the idea of buying another friggin plastic tank. I don’t like the idea of cutting into my s14 - as it’s still rust free and pretty factory when it comes to the body, but I think a fuel cell is my likely answer.

[afishysilvia]

Have you confirmed a fuel tank leak? Does it leak only when full? Have you checked the fuel pump hanger/top hat. The Zenki s14 have terrible leaks there from around the actual electrical connections.

[dorkidori_s13]

I sent an email via Nissan USA's website about this problem... who knows if it will go anywhere, but I mentioned this problem is occurring world wide.

[FRpilot]

Not sure if anything will occur talking to Nissan USA and not Nissan Japan directly, but hopefully they hear the call and bring it back into production or do a small batch.

Nissan did bring back some r32 parts into production through the NISMO heritage program, but the r32 gtr is legendary. I would think the s14/s15 would hold some kind of meaning too.

[dorkidori_s13]

theres still TONS of stuff you can get brand new for the S-Chassis. i suggest everyone who wants a new gas tank email Nissan via their website contact form and start requesting it. theyve been bringing A LOT of parts back from the dead lately... case in point, nissan FINALLY made a HUGE run of OEM S13 sun roof weather stripping. it was discontinued for over a decade. the ONLY way you could get it was to buy a new sun roof and that was $900. well, nissan got off their butts and made more.

im sure that a problem existing WORLD WIDE would get them off their asses to make more given the gas tank is a VERY important part of the car and without a sealed tank, no S14 or S15 will pass emissions. get enough people emailing about it, they will do something.

[FaLKoN240]

This makes sense considering people are still buying used s chassis and they can't even sell their new line of cars :keke:

Very good suggestion, and apt comparison because this is basically s13 sunroof v2, ha!

I actually got a response from Nissan USA!

im debating on calling them and hounding them a bit... especially since ive got a case number now.

i would highly recommend you S14 guys start bugging Nissan. its now evident they do actually read these reports.

[Kingtal0n]

Somebody with a couple hours to kill should look up all the fuel tank dimensions for every car ever made and find one that is compatible.

There has to be one in something that will fit nicely. There just has to

Okay, I did my 5 minutes of research:

If everybody does 5 minutes of research it should only take 12,000 members 5 minutes each to do 1000 hours of research, which should just about do it...

allllriiiight!!! so excited.

im being sarcastic, because lately parts prices have gotten very unrealistic. nissan is not the only manufacturer to blame. to be honest, all the manufacturers have hiked prices up so much that its making build and/or restoring cars a fucking nightmare.

i really dont understand it nor do i think any manufacturer has justification in these price hikes. NISSAN motorsports in particular can eat a big bag of dicks for the way they've inflated all of their prices for JDM parts. not only do they not give you ANY lead time on how long these parts will take to arrive, then they rape you on pricing.

when this happens, i'm all in for (quality) aftermarket solutions.

[mav1178]

working on a source.

will update when I have results.

This is similar to the other thread about OEM genuine S13 Silvia fenders, let's see if any of the suppliers can come through on this.

[mav1178]

is anyone actually serious about buying brand new genuine OEM fuel tanks?

seems like I can order it, but 1) it's $550+, and 2) 180+ days out.

will order one to see if it actually comes in, but buyer beware.

[TheRealSy90]

Are you actually going to order one? Or did you mean you'd order one if someone wanted it.

I ordered one to see if it can be fulfilled... meaning if I get it in 6 months, it may be same or higher price than what I was quoted because the lead time is so long.

6 months is enough time for the global economy to crash.

Did you order it online or at the dealership? Mine just bit the dust tonight.

I'm sending my girlfriend to work Monday with the part number to see if the parts guys can give me any details on if any are left in the country and how may there may be, if any.

I went ahead and sent in a customer affairs email. What's it going to hurt?

Oh yeah, still looking for the parts mentioned in my signature.....

I'm not ordering it from any source within North America.

I'm interested in the outcome of this. I'm sure you won't leak your source of the overseas parts? I've never ordered any parts from overseas vendors that didn't come from a site like eBay. I'd love to learn YAJ but that is a whole 'nother topic.

I just went and picked up a used tank from a local (2 hours away) yard that actually had a S14. It looks good with no staining indicating a fuel leak. I am going to use that tank while I plastic weld my original and give that one a go once more to see how it holds up.

I guess let me be more specific...

like the other thread about genuine S13 Silvia fenders, I'm ordering to see if it can be fulfilled. If it can, I'm stocking a few to resell.

There's really not a secret to this. If someone wants genuine parts, either 1) it's available via the proper channels in North America (or discontinued via that same channel), or 2) it's available in another territory overseas (or discontinued via that same channel). Parts inquiry are fairly straightforward, if it's not listed as EOL you can definitely order it, fulfillment is entirely another story.

Other regions may have parts makers producing them locally and sold as "genuine OEM Nissan", so for all intents and purposes it's identical to what you want (except it may be made in India or Malaysia or Chile or France)... but like I said, 6+ months wait.

That's interesting.

I've worked the shop side of dealers for 12 years, and had plenty of times where the parts department said it was discontinued and no longer available to order since there was none in the U.S. When they tried to order, the next days report would show the part order cancelled (happened plenty of times with ordering MR2 parts).

If the part showed 'National Backorder' status then they could order it but like you said, it could be six+ months. I never had an overseas option. I wonder if that's a specific dealer thing? I've never had a dealer be able to order overseas.

At this point, I've owned this car 12 years so getting the new proper parts to keep it going and able to restore the thing a bit would be so nice. What's another 6+months after owning it this long?
