Cracked fuel line

So, driving in downtown columbus proved disastrous. When they mean steel plates ahead, they fuckin mean STEEL PLATES AHEAD

So my exhaust came off but the real problem is that I'm leaking major fuel from one of the lines, about ten dollars worth a night, and I have to put in 20 a day after driving about 20 miles.

Question is what kind of options do I have? Worth it to go steel braided? Do manufacturers make pre bent hardlines? Do I buy new lines and bend them myself? Solder? I'm low on money.

Thanks

id find out where in the line is it coming from, supply line or return and what section, if its coming from a rubber section replace it with fuel rated line that wont deteriorate. i dont think steel braded is worth it, not needed for the relativly low pressure fuel line sees. i was in my infiiniti once and i hit something and tore open one of the metal lines , this was in the middle of the winter and i had no garage , or even tools at the time. next day i got my scissor jack, jacked it up, took a pipe cutter tool, ( the kind u spin around a metal pipe and it cuts it, to cut out the damage section , maybe a foot or so) so i removed the bad section, make sure u use a pipe cutter or something that wont crush the line, this is a spot where you dont want to use pliers or diagnal cutters to cut, because it will crimp the line shut and that will get u no where. so get out the bad section and i tool rubber fuel line and replaced the metal section with the rubber line under the car. it was dirt cheap cost like less than 10$ and i did it in like 30 mins, i cut out the bad, put in new rubber line for about a foot, double clamped it on each side and it was fine, it did not fit neatly into the line tray again, but meh it was cheap and lasted, in my opinion the best way would be to replace the whole metal line, if you have time and the $$, still not at expensive route either. if the rubber line leading into the fuel pump was damaged, thats an easy fix just replace it, thats my 2 cents, keep me posted

Fix all fuel leaks ASAP. Fuel + hot exhaust = fire.

The best thing on a budget is to go to a junkyard and pull off the line you need. Find out which line is broken first though.

just take it to a shop and have them do it for you.. they will most likely have the proper hose you need or can get it for you. you don't always have to do things yourself! or you can get them to source where the leak is coming from and then do it yourself anyway..

if it's a rubber line that ruptured, replace it....

if it's a hardline that ruptured, replace it....you can go oem if you want...or you can get hardline and bend it yourself. there's a tool to make a lip on the end of hardlines too, forgot what it is.

flare tool. most come with a line cutter too.

you can get a coupler or two and replace only the small part that has a hole, or just cut it, put two ends on it, flare the ends and put a coupler on in it's place.

have done that on my buick where a brake line rusted through. you can buy sections of hard line at the auto parts store in different sizes and thread pitches.

Thank you everyone, I'm going to go to the junkyard later this week and check out their supply of 240sx's.

If that doesn't work out, I'll go the cut plus rubber hose route

that still might leak if its one of the high preasure fuel lines. if its not you can get away with it. if u get a used line make sure its not clogged with old fuel carroding it. clean the tip and blow thru it to check for easy air flow.GL

If you're gonna work on your fuel system, do it right the first time and don't skimp on the costs.

Seriously, it'll save you so many headaches. I learned my lesson the hard way. I tried fixing a hole in my gas tank with epoxy and that steel clay stuff. Big mistake. Orange County Fire Rescue had to come out and "drain" my tank for me because it was leaking so bad. Also, use the correct size clamps/hoses. I was using clamps that were just a little bit too big and I was losing fuel pressure from the fuel filter. Took me forever to find that shit. Oh, and I probably wasted ~$100 worth of 93 octane fuel.

But yeah man, if it has to do with your fuel system, do it right.

Get some hardline from the local auto parts store and rent a flare tool or something. It's not too hard to fix.

just replace the hose from auto parts store. shouldnt take more than 40min.
