Was getting it ready to start today and found that my injector o-rings are too small on the fuel rails. I jumped the terminals for the fuel pump relay to get some fuel moving, and all the injectors leaked at the rail. Anybody had that problem before? If so, whats a compatible o-ring thats big enough to hold fuel pressure?

Ya ran into the same prob when i went from stock rails to the fast ones. I cant remember the size tho, i know they are light blue lol. Call Jon at FIC he told me what i needed.

I am using the light blue ones....they felt like they had a loose fit when I first put them in...

Just went out and checked something, the light blue were right on stock rails, sorry i just realized you are using aftermarket rails. Ok pulled the rail real quick, they are dark green, hope that helps.

Maybe they have single o rings you can try at the dealer. Take your injector and rail.
