FP Gauge Install

[my97mitsGSX]

does the FP Gauge get installed before or after the fuel rail. I thought you tee'd off the vacumn hose from the FPR to the FP solenoid on the car.. the blue dotted vacumn line

I think if you installed the fuel pressure gauge after the fuel rail it wouldn't read much (if anything). that is if by "FP" you mean fuel pressure gauge.
