Fuel Pressure Readings. FYI

I just replaced my fuel pump at 117,000 mi. Truck is running great.

Starts like factory new.

Fuel Pressure readings:

Key on, no start = 55 psi

Engine running normal, idling = 48 psi

Engine running, pull vacuum line from fuel regulator = 55 psi

Engine off, holds pressure for about an hour or two, goes to zero.

Gauge is a Actron #cp7818 test kit, bought at Pep boys for $40.00.



I was thinking the same thing.

Not sure how I'm going to check the accuracy of the guage.

But the truck does seem like shes back to normal.
