Any know what the average fuel pressure for our cars are after the fuel damper? I guess I can hook up a fuel pressure guage to the SPX fuel adapter I have already in place, but I figured someone might know here.

-Digital Nitrous Pressure Gauge & A/F Switch/Gauge
-Pressure-based Bottle Warmer

I aked the mech who installed the Vortech sc on my car , when I picked up my car. He said he hooked up my gauges and the stock fuel pres. was reading around 35 lbs .After the install , with second fuel pump...it read 50 lbs

Couldnt afford it when young...gonna play when Im old

 

For what its worth...

Page EC-46 of the 2003 Sedan shop manual states the fuel pressure at idle is supposed to be approximately 51 psi.

My car was running at 55 psi when it was stock. 50 with FI seems a little low.
