Fuel Line Repair/Replacement

[Preston_08]

Having some leaking in both lines where it bends to go up over the back axle and was wanting to replace both complete lines. Genuine parts are outrageous, but I did find a whole kit for relatively cheap from Fineline Fuel Lines. Anyone ever use these? Thanks for any input.

so i just got this and will tell you what i did. i cut the lines up ahead of the rusted area towards the engine along the frame and installed hi pressure gas hose, then i got some tubing and bent it to go around the bend and cut the line about 6" from the filter. and attached some hose there as well. i guess you can just use hi pressure hose for the complete repair for both lines. also check real god at the tube going into the filter. mine was so bad that i had a gas leak at the filter and had to get a pc. of line with that push on lock in the line. that was 14$ at the part store so hope your line id ok.

it is a bitch to repair in that area. had to take the power lines off the evap canister and the tubes off as well. then i took the filter off to get room. so as you inspect that area you may decide to just go with rubber hose. make sure it is hi pressure gas hose. there may be a you tube or so on doing this if you do a search there is a bunch of talk on repairing these. some are rusted some are rubbing the line also. good luck

This happened to my daughters 07 cobalt. It started leaking just in front of the drivers side rear wheel. I took it to a guy I know and he patched in some fuel line just like corvairbob. The guy said it was pretty big job as well, but it held for over a year and she just traded it in on a 2015 Cruze.

Yeah, not on my Cobalt, but I used fuel tubing (the rubber stuff) to patch a short stretch of broken line on my Accord once. It worked, but any rock or sharp object that gets kicked up there could give you a bad day. That's why they make them out of metal, of course. And if you are in an inspection state, not sure it would pass. Sorry that you have that situation, but good luck to you.

no reason rubber would not pass a state inspection. the line is rubber from the tank to the filer and most likely rubber at the engine. they use steel as it is cheaper. rubber will take more abuse than steel. but cost more. and if rubber was cheaper they would fine a was to stick it up inside some protection.

I believe there are reasons they use steel other than cost. However, when I had my daughter's cobalt fuel line patched with rubber fuel line, it was simply due to economics. It was a lot cheapter to patch in a few feet of rubber fuel line than replace the entire run of steel.

My daughters 2009 LT had a leaky return line at the rear drivers side, ahead of the back wheel. Taking off the heat shield I could see the leak and how much both lines were corroded, not only under the heat shield material, but several other places from about the center of the car up and around to the gas tank.
I got a set of nylon lines from Inline Tube, and replaced both lines. The kits comes with a new filter and appropriate fittings already attached, and cost about $100. In total, I figure I replaced about 12 feet of old line. The hardest part was cutting the old line out, and fitting the heat shield material back in and wiring it in place. If I did it again, I'd try to cut the old line out while keeping the heat shield material intact (it's a tube) and thread the new lines through it, then wire it in place.
