Loosing Fuel Pressure
I added a Schradar valve to the back of the fuel bowl to check FP. When I turn the key on I hear the pump. The pressure rises to 52 psi, pump shuts off, holds pressure for 5 seconds then pressure drops to 30 psi. Is this a symptom of a faulty FPR or something else? I didn't see any leaks. The truck is a 99 with 48k miles and all original. Truck did sit for about 2 years with out starting and of course ran fine before. I also cleaned the fuel bowl.
