DIY Fixing a leaking Fuel Filler Neck Tube with Fibreglass

- For 4 years my 2001 Chevy Tahoe has had a P0440 Evaporation System engine code that comes on triggering the check engine light in the dash. Also, I could smell gas immediately after every fill up but there was never any fuel dripping on the ground until recently.
The 4 parts stores I called wouldn't sell just this rusted out metal tube. Instead they could only sell the metal tube, rubber hoses and the gas cap metal assembly for $450-500. This repair shows how to prepare the old metal tubes for fibreglass and also shows some techniques for competing the job.
After a month, there have been no more leaks after fillups. The check engine code did not automatically go out so I used a code reader to manually clear the P440 code and the light hasn't come back on :)
could always use a exhaust elbow and use a mig welder to run a bead on each end to make the rib for the clamp to grab
I use chop strand mat to do curved auto body work , it's messy but the fibers give and shift
to contour to the curve of the piece your working on
Alright! It Will Work For Ya! Great Idea!!
No More Leakes!!
I did my filler pipe, 2009 cobalt, with fiberglass. After I did it i thought of an idea of putting the fiberglass on dry, then wrap sewing thread around it to hold it in place , then brush on the resin.
Good idea. That would be fine provided you use multiple layers, which should be done anyway
Thank You, For Sharing!!
See you On NEXT ONE!!
Love the thinking and the DIY but I think I'm just going to the junkyard and getting another one for 15$ haha
02 Chevy trailblazer p0440
I tried that and the 3 vehicles that were checked had filler necks in terrible condition.
Great JOB!!
its a good repair but gas generates static electricity as it moves thru a pipe. Probably nothing will happen but using the wrong type of rubber or material could cause an explosion. Those materials are tested extensively.
Good job.
For the same money on the cost of the fibreglass Go online buy the filler neck Even in 2015 that filler neck is no where near $500 .. another would be the auto wreckers Fibreglass breaks down with gas on it
The Main thing, Is It Will HOLD!!
Holy Hell
is the repair still holding ? i have to fix mine , they charge me 200$ just for the hose 300$ for the metal neck + work time100$h ... found boat fuel filler hoses for 60$ i can use but looking for a definitive fix for the metal neck since its gonna be a freaking pain to get of
My repair is holding up fine. The fiberglass covered pipe will likely outlast the vehicle.
How ABOUT!! The Thickness??
Go to a muffler shop and they will make you a pipe for 20 bucks
Thank you David. I will just go buy one. Although the video is nice...Your comment is more helpful than the video. I don't have any of the materials needed. But...if all else fail, I will replay this video.
Hi MsQueen. Did you get the filler neck pipe at a muffler place? I have the same problem right now.
get your gas from somewhere else has to be full of water cheap gs is cheap
no, that is from the damn salt they put on roads. It eats cars away.
try it oat
