Where is the fuel pump valve on a Ford?
As I mentioned at the beginning of this tutorial, Ford installed a Schrader valve on the fuel injector rail. As you can see in photo above, this Schrader valve looks just like a tire valve stem (the one used to air up the tire). It’s to this Schrader valve that you’ll connect a fuel pressure test gauge to, to check the fuel pump’s pressure.
What should the fuel pressure be on a Ford 4.9L?
With the key on, engine off (KOEO), the factory manual says fuel pump pressure should be between 30 to 45 PSI for the 5.0L and 5.8L V-8 engines. The KOEO fuel pressure for the 4.9L 6 cylinder is 45 to 60 PSI.
How does the fuel pressure regulator work on a Ford?
The fuel pressure regulator controls the fuel pressure in your Ford’s fuel system, maintaining the proper pressure needed for your vehicle to run optimally.
How do you test the fuel pump in a Ford?
Connect the fuel pressure test gauge to the Schrader valve . With a shop towel, mop up any fuel that was released during the process of connecting the fuel pressure gauge to the Schrader valve. When ready, ask your helper to crank the engine while you observe the fuel pressure tester’s gauge.
What kind of fuel tank does a 1992 F150 have?
I have a 1992 F150 4×4, dual tank, 5.0L, with fuel injection. There are two high pressure pumps, one in each tank. There is no third pump on the frame rail. There is no distribution valve on the frame rail.

Where does the fuel come from in a Ford F150?
It seems the truck is drawing fuel from the rear tank, even though the selector switch is set for the front tank. I have gotten under the truck while a helper turns the key to the on position, engine off. The front pump runs for a short burst when the key is turned on and the selector switch is set for the front tank.
