Items you will need
Floor jack and 2 jack stands
Ratchet and socket set
New fuel tank mounting studs
On average, electric fuel pumps have a long service life, but eventually internal components wear out and develop leaks, low pressure or no pressure at all. Follow these simple steps to replace the failed electric fuel pump on your Ford Crown Victoria. The procedure is based on a 2000, 4.6L engine, which is similar to other models.
Park the vehicle in a safe place and make sure there is enough room around the back of the vehicle for you to work and move tools around.
Start the engine and let it idle while you relieve the fuel system pressure by removing the fuel pump fuse or relay from the fuse box. Wait a few seconds for the engine to stall, turn the ignition key off and replace the relay or fuse.
Raise the back of your car using a floor jack and support it safely on jack stands.
Disconnect the fuel tank filler pipe and the fuel pump connector located above the cross member underneath the vehicle.
Disconnect the vapor tube from the tee connector on the right side of the car-passenger side-and the vapor line from the canister tube.
Support the fuel tank with a jack and remove the nuts from the holding strap using a wrench or ratchet and socket. Move the strap away and lower the fuel tank. Discard the fuel tank mounting studs.
Unplug the pressure transducer electrical connector located on the top rear corner of the fuel tank.
Clean the area around the fuel pump mounting flange and remove the flange mounting bolts in a crisscross pattern.
Lift the fuel pump assembly off the tank. Replace the new fuel pump in the assembly and install the assembly in the tank. Install the flange screws and torque to 89 inch lbs. (10Nm) using a crisscross pattern.
Raise the fuel tank to its mounting position, install the strap using new mounting studs and torque the nuts to 26 foot lbs. (35 Nm).
Connect the fuel pressure transducer electrical connector, vapor tube to the tee connector, vapor line to the canister tube, fuel tank filler pipe and fuel pump electrical connector.
Lower the vehicle, start the engine and check for leaks.
Do not allow smoking and park away from open flames like water heater and dryer whenever you have to work on or near the fuel system of your vehicle to avoid an accident.
