Injectors leaking at fuel rail.
I have 30Lb Venom injectors in my L98. I have replaced the o-rings twice, but keep getting leaks at the fuel rail. The last o-rings were GM factory blue Vitons. Was thinking of going with different injectors, probably back to 22Lbers. Any thoughts?

Re: Injectors leaking at fuel rail.
What was the reason for the 30# injectors? Running boost? Anyway, make sure the fuel rails are clean too. You might have something in there that could be causing the leaks. Also, make sure the o-rings are in good condition when putting them in the holes. Use a silicon base lube spray to help get them in easier.

Re: Injectors leaking at fuel rail.
At the time I didn't how many horsepower the stock injectors would support. When I rebuilt the engine I carefully cleaned the fuel rails. There is leaking from more than one injector also. Will probably go with a matched set of 22# from FIC anyway. Thanks for the ideas!
