I recently purchased these injectors that have the red top and grey bottom. After having them reconditioned and flow tested I went to install them on my car and thats when the questions came up. First off, the o-rings don't go nearly as far into the fuel rail as the original injectors do and I was curious rather or not others who have used these injectors ran into fuel leak problems. If I had to take a guess, I'd say the o-ring only goes 1/8 - 1/4" into the rail before the clips attach to the injector. Any help would be appreciated, thanks.

 

you should be fine. as long as the seal is w/in the port of the rail and intake injector bung you should have no leakage issues.

 

Yeah, the injector seats in both the intake and fuel rail, but I wasn't sure if it would be alright for the injector to only go such a small distance into the fuel rail. Thanks
