O-rings inside fuel rail quick disconnects
Like the title says, I need replacement o-rings since the olds ones won't hold fuel pressure and are seeping fuel all over the engine. Local GM dealer here can't even find a part number for them. Anyone have any suggestions?
Thanks.

Re: O-rings inside fuel rail quick disconnects
I didn't install new ones. The o-rings are original. I've had to remove the fuel rail a few times since I've had the car to deal with injector issues and to replace the manifold gaskets. I'm guessing that after all the removals and installations the o-rings have either dried out or I've damaged them somehow.

Re: O-rings inside fuel rail quick disconnects
Hmmm... Looks like it could be it. The description says it is for inlet and outlet, but the inlet and outlet are different diameters.
 However, my old man, the greatest parts guy in the world, found a dorman kit that should work part# 800-060.

Re: O-rings inside fuel rail quick disconnects
Go to your local auto parts store and ask for HNBR O-Rings that are compatable with R134A refrigerent. The HNBR material is resistant to just about anything including gasoline. I replaced both sets of O-Rings on the fuel rail on my 00 LeSabre about 4 months ago with HNBR rings and they seem great so far, no leaks. They were extremely frustrating to pick out and replace, required lots of patience and a steady hand. The best part of using HNBR O-Rings is that most auto parts stores stock a large variety of sizes for people doing R12 to R134A A/C conversions, they're typically green or blue in color. If you research the HNBR material you'll find that it outperforms just about every other O-Ring material used, in my opinion, that makes it a perfect choice for just about any application.
