Fuel leak 2004 cracked crossover connector smells
#22
I put a link in post #13 that has pics in it of my fuel filter with leaks you can see. On mine the smell of gas was strongest near the rear of the drivers door (same location as the filter). Good luck getting your fixed.

I had the same problem with my 04 ce a couple of years ago.
I spent alot of time trying to find the leak. Replaced stainless steel crossover pipe, put transaxle back in and it still leaked when I filled over half a tank.
Problem was the left hand tank had a hairline split on top of the crossover pipe connection.
After years of seeing this problem on the forum, it should have been a recall by GM.
They changed the whole fuel tanks setup for the 04 models by using a stainless crossover pipe, instead of fail safe rubber and installed the fuel filter inside the tank. I think this was done for new laws introduced and I think it's the same setup in the C6 now. Why did they have to do it on the C5's.
Haven't had a problem in years but I still get worried when I fill up.
Good luck everyone.

I have had the smell but never found the source. After having the car on a lift, i saw where the fuel was coming down and staining the bottom protector plate. I never found any fuel on my garage floor though.
On a trip, i was filling the car up and decided to just look underneath. I saw fuel leaking to the ground as i was filling up. Thankfully i didnt have any problem past that and it doesnt leak at any other time, just smells. So i fill only to 1/2 and do it slowly right now and i have not had any problems with smell or gas station leaking.
Has anyone revcd. anything from GM concerning the 04 problems? It sure seems to be mostly 04 that are having this problem.

Well heres where i am,,, i looked on the nhtsa.gov website and instantly found 10 hitswhich i documented.... i documented as many as possible on here.... I also found a Youtube link of a 2004 burning to the ground for no apparent reason and was obviously not able to be attributed to the tank after the burn but seems obvious to me.
bottom line is the 2003s had a rubber hose connecting the two saddle tanks,,,, it is NOT the fuel filter NOT the gas cap, NOT the plumbing...
It was changed to steel on two reasons that i read 1 EPA said the level of hydrocarbon being released into the atmosphere by rubber hosing was above limits. 2 there were many complaints of fuel smell in the passenger compartment. I dont know which it was but they change to braided steel.
the tank connector on the end of the hose is a twist lock bayonet style and has two o-rings that seal the connector,,,, it does NOT leak,,,,, the more rigid crossover hose breaks the plastic moulded connector on the tank. this connector is plastic welded to the main tank.
as for the dealer he was a jerk,,, Kendall Chevrolet,,, the service manager used mitchells guide to estimate the time.... i asked why he was not using th GM book and he told me that was only for warrantee,,,, i got him to reduce the time to 6hrs for a job that took around 2 hours.... remember he told me the transaxle had to come out.10.5hrs ..he had the standard BS used car salesman attitude...
so i called GM to complain about the faulty parts and the cost of the labor and the lies that were told to relieve me from my money...
GM listened to my complaint with the standard off shore " I am sorry for your trouble" " i will help you , I am assigned your case" blah blah after three weeks and two reps "regional service reps" I told him that i needed to speak to someone in detroit and i was going to start calling PBX extensions in the detroit offices until i got someone to listen....
the third rep said he could not offe any relief on the part (which is what i wanted since NTHSA entries indicated that the rep or dealer reduced or eliminated the cost of the tank on the repair).
he offered coupons on the next car i buy,,,, all kinds of options...
I will post my final decision once i have it in my hand however i bet if you pushed harder and used my information you would be able to do better than me since i was out of patientce..
i have a huge file that could be scanned and distributed if anybody wants it
my total cost on this was 1450...

I am afraid that until the Gov forces GM to recall these cars,the dealers hands are tied.After all they did not build them.That is why all 2004 Corvette owners need to go to the site and register a complaint.
