Thread: prj fuel rainl/ injector help

so I installed them they leaked I started changing injector o-rings with the o-rings zzp sent me for the swap but the o rings almost seem smaller than the old ones and when its all bolted down I can rotate the injectors I havent tried turning the pump on but do you need special O-rings for these rails or something

Punctuation, for the love of god. Get bigger o-rings. Or get smaller fittings from Xtreme Racing Plumbing.

nope stock o rings. injectors are able to rotate when installed, thats normal. just make sure the orings didnt get pushed out of the side or anything.

I've always just used regular Felpro's. I think they are ES70599's. Whatever it calls for on our cars. Put them on, then lube them up with vasoline. Slide injecftors into rail and rail onto motor. Bolt down.

bill did you just pull that number off the top of your head.

Yeah Brian...I did.

FWIW, it's right too

alirght one of the o-rings was defenitly bad but while swapping them I noticed that the second nut on the hose connection don't know what its called was losse on the front and back rail so that might have had something to do with it

The injector fitting piece. Yes..that'll cause a leak.

ok so I hooked it all up and now the only leak I have is where the hoses go into the regulator adaptor will thread sealant hold up to gasoline?

In my experience Teflon tape works the best.
