well i have built my fuel sytem for my 8 inj system. i am running both rails in paralel and a single return out of my FPR, with both rails going into the FPR seperatly. my qestion is where do i put my fuel pressure gauge sender assembly to read my FP.

keep it on the primary rail line? secondary rail line? on the main feed line before the "T" to each rail?

help!


thanx

Theres not a fitting on the FPR? Mine has a seperate fitting right on the FPR body. I would try keeping it as close to the FPR as possible but it shouldn't matter whether its on the primary or secondary line. The pressure should be the same in either as long as the lines flow well.

yea keep it as close to the in port on the reg as you can

i have a port on the FPR (aeromotive 1:1) for a gauge, but i meant for my electronic autometer one in the car. either line as close as possible to the FPR will be fine? does it matter when im in boost which line im on, or will they both read the same FP in or out of boost?
thanks
guys

Either side should read the same in or out of boost.

If I were you I would put the electric sender on the FPR port. All you need the mech guage for is for setting idle pressure. So you can do that by connecting to the test port, because you should only have to fiddle with that once. Once you set the pressure at idle to stock pressure then from there on out you adjust everything on the EIC anyway. Does that make sence??? This is not like the SFMU where you will mess w/ idle FP all the time to tune..
