Fuel tank vs fuel cell

[Guilty1s]

In my opinion, the design of the s14 fuel tank is pretty damn good for a rwd car. The drop in fuel pump sits at a super low point in a very narrowed down part of the tank. It's also made out of plastic and not metal bullshit.

I'm looking to push 600-650 on the new setup (drift) and was definitely upgrading from the setup I had at 450whp, which was stock fuel tank and a walbro 255 with bulkhead fittings at the top running 6an lines with a fuel return

New setup is gonna include a large surge tank and likely a 044 pushing it through.

But what reason do have to swap out to a fuel cell.

I could run a drop in in-tank walbro or aeromotive 400 to supply the surge tank
It sits in a very safe an weigh conscious position
I believe since its plastic it should handle e85 with no problem.
Even though it's a saddle design, it's still seems pretty mindful of a drift setup and the surge tank would pretty much remedy anything that would be a problem.

It's a 100% track car, but unless I'm missing something or mistaken, I can't find a good reason to switch to a cell other then the ease of draining. Someone please correct me if I'm wrong.

Only reason I see to swap to a cell is the safety of a bladder system and the ability to locate the weight where you want it. The S14 has a pretty desirable fuel tank location, but if you go rear mounted fuel cell it opens up a whole new world above your subframe which is nice.

Finding a replacement could be a challenge, eventually the fuel tank could be discontinued as these cars continue to get older. Fuel tanks are also meant to hold a decent amount of fuel, which can be unnecessary in certain applications. That being said, unless you're looking to replace it with something smaller or fitting a different rear end, the factory tank is sufficient.

Ahh... Rear end clearance... Didn't consider that. Luckily a winters quick change in not even close to in the budget.

Thanks people's... I think I'm sold... Which means I can sell this fuel cell I already bought in the morning

You should reconsider. I love mine :)

I've always avoided it because of the PITA with having to rig around being able to fill it through the stock fender hole, most of them are ghetto rigged and mounted poorly (because where the hell is a good clean place to put a decent sized cell other than stock location), the fuel level gauge would be useless and is pretty damn handy, etc. The later kouki tanks typically don't crack. I've had a couple of each gen S14 and the zenki has a mold line right where they crack. My current 4/97 build tank has a smooth edge/seam where they crack so no stress riser.
