REMOVAL & INSTALLATION
- Disconnect the negative battery cable and properly relieve the fuel system pressure.
- Remove the fuel tank and place it on a bench.
- Remove any dirt that has accumulated around the fuel pump retaining flange so it will not enter the tank during pump removal and installation.
- Turn the fuel pump locking ring counterclockwise and remove the locking ring.
- Remove the fuel pump and bracket assembly. Remove and discard the seal ring.
- Clean the fuel pump mounting flange, fuel tank mounting surface and seal ring groove.
- Apply a light coating of grease on a new seal ring to hold it in place during assembly and install in the seal ring groove.
- Install the fuel pump and bracket assembly carefully to ensure the filter is not damaged. Make sure the locating keys are in the keyways and the seal ring remains in the groove.
- Hold the pump assembly in place and install the locking ring finger-tight. Make sure all the locking tabs are under the tank lock ring tabs.
- Rotate the locking ring clockwise until the ring is against the stops.
- Install the fuel tank in the vehicle. Add a minimum of 10 gallons of fuel to the tank and check for leaks.
- Install a suitable fuel pressure gauge on the valve on the fuel rail.
- Turn the ignition switch from OFF to ON for 3 seconds. Repeat this procedure 5-10 times until the pressure gauge shows at least 35 psi. Check for fuel leaks.
- Remove the pressure gauge, start the engine and check for leaks.
- Relieve the fuel system pressure and connect a fuel pressure gauge to the valve on the fuel rail.
- Ground the fuel pump lead of the self-test connector through a jumper wire at the FP lead.
- Turn the ignition key to the RUN position to operate the fuel pump.
- Observe the fuel pressure gauge. The indicated pressure should be 35-40 psi.
- Remove the fuel pressure gauge and the jumper wire.
