Stock fuel pressure at 52 psi

[idt512]

I spliced into the line from fuel filter to fuel rail inlet and Tee'd in a pressure gauge, and i get 48 psi with the FPR line connected, and 52 psi disconnected. It is a stock fuel regulator and the car runs and drives perfectly fine. Should i correct it or leave it alone?

The gauge i used was from a pneumatic air pressure regulator from my work, the regulator portion broke and they were going to throw it away, the gauge was functional so i figured it would be ok to use... Does it have to be a FUEL pressure gauge?

you need a FPR to control the 190lph pump you have.

This is happening with the OEM fuel pump. I know my profile says Walbro 190 but that was from a car i had years ago and im unable to change my profile.

oh ok, yeah i'd just leave it alone then.

Is the location of where the gauge is placed critical? Does it make a difference if its placed BEFORE the fuel rail? The aftermarket AFPRs are AFTER the rail and im wondering if the reading would be skewed because of that.
