Engine/Transmission (1994 - 1998) Fuel Pressure

[nfox]

I am getting ready to install my fuel pressure gauge and was wondering what kind of fuel pressure i should see on my 96 5-speed p-7100?

nfox,

No less than 25 psi on supply side of fuel filter(tank to filter) and no less than 20 psi on supply line to injector(filter to injector pump) at idle. As you increase rpm fuel pressure should rise. I believe I have read 30 psi at 2000 rpm.

Idle pressure is overflow valve as is 2000 RPM pressure, WOT throttle pressure is fuel pump. Mine is at 20 idle, 28 at 2000 and 17 at WOT but I'm pulling allot of fuel at WOT too.
