I have a set of fast fuel rails, Need to know which fitting i need... I have a standard nitrous system... I need the fitting that removes one of the block off plates of the fuel rail and feeds fuel to my fuel feed line.... I dont know what a/n measurment the line is but i do know it is the one that srews on to the factory fuel rail!

So im guessing -6an..... If so F.A.S.T gave me part # 54023B
Thanks chris

 

The feed line off a factory rail is a 4AN. I'm not sure what the NPT size is on the speed inc rails but I would guess 3/8NPT?

F.A.S.T does not have them, and i found one place on the internet that does but there out of stock... So if anyone knows were i can get one lmk

Russell Performance 660060 should be what you're looking for. Try summit or jegs.
