Fuel Pressure Gauge

Scrapla · 01-02-2003, 12:49 PM

I just inastalled a fuel pressure gauge, the one that connects direct to the shrader valve under the hood, what should be reading be on a almost bone stock engine with stock 19#ers.

At an idle it should read high 20's to low 30's. @WOT or '0' vacuum it should read about 38psi.

Dark_5.0 is correct

and just incase you weren't aware, the way to check the pressure at 0 vacuum is to take the vacuum line off of the fuel pressure regulator and then check it

should be anywhere from 37-40psi with the line off
