LS7 Fuel Rail fit's what Intakes? I've been getting a lot of questions regarding the LS7 fuel rail on non-LS7 manifolds. I actually don't know myself and would like to find out. Does anyone know if it will fit on the LS1/2/6/76 intakes? My concern would be injector height and bolt pattern. Thanks!

That's correct, the angles are different on the LS7 from any other rail....also the spacing where the fuel rail actually mounts to the intake varies slightly on the LS7 from the others.

Nate, where have you been with this, I went with a Fast fuel rail to provide a flow- thru parallel system for my LS7. Because the stock injectors are small in height the fuel rail didn't fit. Changed to Bosch 44.5# injectors which provided the size to make the rail fit and system work. I'm glad to hear you are providing an alternative.

tried your # but got msg mach. We took the injectors and fit them into the manifold and looked at the angles, spray pattern etc. Determined that none of the fuel spray ended up on a surface but would spray into appropriate space. Fitted the Fast rail with custom brackets and then used Katech O-rings. They fit without problems.
Chose the Fast rail for OD size and flow thru design. What is your rail size? That's a good price on the rails.
