You should have around 60 lbs at the Schrader valve while engine is running.

not to disagree with Tom, but I think stock it will run just fine on 40-45 psi. preferred pressure is 55-60, but you may have to do the old BB mod to get that pressure out of the regulator

My '96 has always run at 50 psi. I've read this is normal for a nonCalifornia truck, but that trucks delivered in California run higher, maybe 60psi+, because of different injectors needed to satisfy the regulators there.
