When I took this apart, all the seals (2 o-rings and 2 plastic seal pieces) pulled right out of the nylon hose and stayed stuck to the metal fuel line. They didn't look damaged and maybe they were just installed wrong in the first place, but I have no intention of taking chances with it. I ordered the part at the dealer today and it should be here tomorrow. It will include all new seals. Now if I could get my cars to stop breaking for a day, I would be in good shape.

To follow this thread to its conclusion, the new fuel line is installed and it has fixed the problem. Fuel pressure stays constant after the pump primes the system, the car fires right up with just a touch from the starter, and the leak is completely gone.

Good to hear, what was the cost of the lines?

Cheers,

For a 1.5' piece of nylon tubing with new quick connect fittings, GM gets $50.70 + tax. I was expecting expensive, but this was even more than I had reasonably expected. At the same time, the car is dead without it, so the bullet got bit.

Glad everything worked out for you. I have a gas leak on my 94 over half a tank. Mine might be the seam, but theres a gas leak stain on top too. Might be leaking from both. I'll be posting about my findings when the time comes.

Now happy driving and hope nothing else goes wrong for ya.

I was at Advance auto last week and they were putting out plastic fuel line repair kits for GM cars.
It was in the help section with door handles and molding clips.

I think I would rather pay $50 for the original line than $15 for a patch job.

Sure would be nice to see how GM assembles the plastic ends in to the plastic fuel lines.

Yeah with something as potentially dangerous as a fuel line, I don't think I am going to take a chance on a cheap patch kit. And in this case it was a problem with the end that caused the problem. I supposed I could have just wrapped the whole area in duct tape, but that might have backfired in the end...
