All, found the correct Viton o-rings for the fuel line quick disconnects on the supercharged Grand Prix. They are working fine so far, no leaks! Bought them at AutoZone, looks like O'Reily's also carries. Call ahead, may have to special order. Recommend also buying the mechanics pick set (dental like angled pick, very helpful with removal)
Dorman #800-013 (2 @ 5/16 & 3/8)

Good replacement "how to" is found in this forum on this link:

Nice to know this was a problem for others too.I actually had fuel in my lower intake pockets when i changed mineThat was two years ago when it only had 208k on it...lol. That rear connect just gets so much movement from the motor rocking.BAD DESIGN

I used the dorman nylon lines. Part # 800-58.

If you have the Harbor Freight O-ring assortment those are fine too, since the kit contains both sizes. Nitrile O-rings are OK to use with fuel also, see this article on using them in carburetors.

i found a set of assorted vitan O rings, they are fuel rated. the black ones are not, they will fail over time. found them at napa.

I got the $10 Viton o-rings and I must have scratched the inside of the connector....it leaks no matter I do. Going to plan B with the Dorman nylon line that I can splice in.

does it click when you push it on, then move with no fuel pressure on the line yet, like back and fourth? its should.
you may have the wrong O ring in there, mine fell apart when i took them out, it was pretty hard to match up the new ones. i used the wrong larger one the first time around.
the smaller one was about the size of the rail end too.

Dorman 800-059 is the rear line, the splice was a ton easier than trying to perform micro-surgery on those O-rings....just a simple barb fitting connects the new line to the old.

my theory on why these cars burn...the cat plugs up, forcing extra hot exhaust up thru the stovepipe, melting the UI and the plastic gas line right on top of the manifold

Sorry.. I don't buy it.
Especially since GM changed the stove pipe design from having almost no clearance to the manifold to having a lot. and the only harm that did was the heat cycles of the plastic manifold would cause the manifold to crack quicker. Which..in turn allowed coolant to fill the intake of the motor. No fire from that.
