Leaking Gasoline
The other day, I noticed a gas smell while driving my C5. When I got home, I looked under the car and found a gas puddle about a foot around on the garage floor below and behind the drives seat. Additionally, I could also see gas dripping at a slow rate from the undercarriage. After letting the car sit overnight, the gas stopped dripping. However, when I started the car up, gas started dripping out again. My conclusion is that, with the car running, there is enough pressure in the line to cause the leak, but after sitting for a while, the pressure drops (because of the leak) and the dripping then stops.
Has anybody else experienced this problem? If so, what was the cause - a bad fuel pump gasket, fuel filter leak? Where you able to fix it yourself? If not, what did GM charge you to fix the problem?
The car, by the way, has about 41K miles on it and at 24K, GM replaced the fuel filter under warrantee.

With all due respect, what difference does it make if anyone
else experienced this problem!?!?!?
You obviously have a serious gas leak and although we can
sympathize with you on your problem, you need to get off you a$$
and get it fixed before you blow yourself up.
If you're not confident enough to evaluate and repair this yourself,
get it to a dealer ASAP.

C5s have had a number of fuel leak problems. I would suggest getting a dealer to take care of it.
The good thing is you have a 98 and the fuel tanks and cross-over is easier for them to get to and fix.

The reason for my question was to see if this is a common problem and what the fix is. Assuming the problem is common, I was hoping that other members were able to fix it themselves and thereby give me some advice on how to fix the problem. Nevertheless, due to the seriousness of the problem, I'll have GM do the repair.

I had this problem on my '04 (but it uses the new tanks). The tanks would drip and puddle after driving, but would eventually stop after the car was sitting for a while. I could smell gas fumes even when no gas was leaking. The problem in my case was leaking gas tanks + crossover tube.

I was have a '98 that last spring was leaking gas just like your car. It was my fuel filter that was leaking. I replaced it, and all was good again. I did it myself, so I can't tell you what it will cost, but I can tell you how to do it.
The problem with the crossover tube seems to be a problem with the '04s....at least I haven't heard of older C5s with the same problem.

I just got my 01 back from the dealer yesterday. Same story, gas smell followed by a puddle. Unless you want to put out a fire.... drive it one more time.... to the dealer. Cost should be no concern.. mine had a leak at the fuel sender and dealer replaced the entire driver's side tank as a result. extended warranty covered it. I paid for the deductible and a new fuel filter. I don't think there is a recall for the sender or tank issue, but there should be based on the numbers of similar incidents on this forum. Good luck

Everybody.........Well, my dealer (Donlinger Chevrolet, Brainerd, MN) thinks it is the fuel filter. They are going to replace the filter and see if that fixes the leak.
This will be my second fuel filter in 41K miles (the first one was replaced at 24K, see above.) It appears as though the life of the filter is about 20K miles and when they go bad, they leak fuel. Due to the potential liability, I am surprised the GM uses a filter that begins to leak gas when it goes bad.
