Pull the rail, unscrew the cross over tube from both sides of the rail. remove the o-rings on both sides and get new ones the same size that will fit snug on the tube. screw it back together making sure that the crossover tube and flanges seat flush with each side of the rail. Bolt it back down and keep an eye on it to see if it stops leaking.

[/QUOTE]I just take off the fuel rail, that #2 oring is tear up pretty bad, every other oring look really good. I find out that one of the fuel injector retainer is missing, can I buy this off part store without going to dealer ?
thanks

The injector clips have one side open and are shaped like a C in the middle. Slide the clip laterally along the rail away from the injector (might be a little tough being on there so long) and once clear the injector is just held in by the upper o-ring and it will pull out (might take a little tugging). Really easy to do and you'll have all the injectors out within mins - you'll see what I'm talking about. FYI - You can buy injector o-ring kits from your local AP or online for wayyyyy cheaper then the dealer so don't think you're stuck with them.
PS: Look in the diagram above and you'll see #19 is one of the injector clips, see how it is shaped like a C and will only slide off one way. The little tabs at the top of the pic hold the clip to the rail and they will keep it there, you don't want to bend these just slide along the rail away from the injector you are removing.

I bought that o-ring kit recently. It's part #17113086. Cost me $6 + shipping from GM parts Direct.
I have my old o-rings still if you want them. I was comparing them with the new one's and they still seemed new.

It doesn't come with injector o-rings. That would be separate. Honestly you shouldn't have to replace them unless they are dry-rotting or cut. But it wouldn't hurt if you had the extra cash.
And I wouldn't use just any o-ring. Those are stiff and I would imagine designed for fuel.

Yeh it comes with both #2's, #15, and #12.
