Forcefedhatch Posted July 22, 2012 Report Share Posted July 22, 2012 Oh that sucks . Just tap em at the end of the rail for a 1/8-27 npt thread pitch. Sent from my iPhone Link to comment Share on other sites More sharing options...
Craig Posted July 22, 2012 Report Share Posted July 22, 2012 Oh that sucks . Just tap em at the end of the rail for a 1/8-27 npt thread pitch. Sent from my iPhone def an option but if it were me id think putting a tee in the line is a lot easier than pulling the intake off, pulling the rail off, drilling, taping, cleaning. new o-rings on the inj. (if u go buy the book) and re assembly. and that is assuming the rails are thick enough to get enough threads in when you tap it so that is will actually work.

SniveTroll Posted July 22, 2012 Author Report Share Posted July 22, 2012 my rails are easily accessible. theres no need to remove intake. only thing i like about the RR 2v intake besides the RPM range. Link to comment Share on other sites More sharing options...
Paul Posted August 5, 2012 Report Share Posted August 5, 2012 Pressure should be measured after the injectors have consumed all the fuel they need to power the engine. The simplest, and most fitting-efficient way I've found to do this (not recommended for 600+ hp applications) is what I have shown here.Feed into the back of one rail. Crossover at the front from one rail to the other. FPR attached at the back of the other rail. Block other port of the FPR. Return line comes out the bottom of the FPR to the tank. Fuel pressure gauge mounted in gauge port.Paul. Link to comment Share on other sites More sharing options...
