Hi, I searched a found a few threads about top feed primary injectors sealing by cutting the top of the diffuser and using that as a seal, but in my own playing with it, it looks like just using 2 of the flat lower O rings would put the injectors in about the right place, and should seal just fine.

Anyone done this?


As far as fuel rails go are there any alternatives to the KG parts rail or is that the only choice?

Thanks..

you and speed of light should talk sometime. he has a bunch of r&d time in the primary injectors and fuel rail.

 

i have the CJ fuel setup.. very good quality and i recommend it. also comes with the adapters to use the top feeds without cutting diffusers and stacking O-rings. it is also the only fuel system that i know of that uses rails that do not look like the KG rails. the KG rails are just made from generic extruded aluminum stock that everyone else uses so the CJ rails give your engine a very unique and "modern" look
