How much PSI does a fuel rail need?
No matter what operating condition (short of demanding more fuel than the pump can supply), pressure in the rail will always be 58psi (or pretty close). When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi.
What are the symptoms of a bad fuel pressure sensor?

What are the symptoms of a bad fuel rail pressure sensor?
How do you check fuel pressure with a fuel pressure tester?
Connect the fuel pressure gauge to the Schrader valve on the fuel rail. When ready, ask your helper to crank the engine while you observe the fuel pressure tester’s gauge. 1.) The fuel pressure gauge will register 35 PSI, or
Where is the fuel pressure test port on a Ford V6?
Location Of The Fuel Pressure Schrader Valve Test Port The Schrader Valve, on the 4.0L Ford V6 engine is located on the injector fuel rail. To be a bit mores specific, it’s on the passenger side of the engine between the ignition coil pack and the upper radiator hose. In the photo above, it’s shown without its plastic cap.
