Items you will need

  • Socket set

  • Catch can

  • Pliers

The 7.3-liter Power Stroke diesel engine was installed in the F-250, F-350 and Ford Excursion starting in 1988, with a turbo version available in 1993. The fuel pump in the Ford Excursion, F-250 and F-350 mounts under the driver’s-side door inside the frame. To locate the pump, use the replacement pump as a visual reference. You don't need any special tools for this repair.

Disconnect the negative battery cable from the battery with a socket.

Relieve the fuel line pressure by removing the fuel filler cap.

Remove the banjo bolt that secures the hard gas lines to the front of the pump. Use a socket to remove the bolt. Some diesel will come out of the pump when you remove the bolt. Have a catch can ready to catch the fuel.

Remove the three hose clamps that secure the hoses to the rear of the pump with a pair of pliers. Pull the hoses off the pump.

Remove the two bolts that hold the pump to the frame using a socket. Discard the old pump.

Place the new pump on the frame rail and secure it with the two bolts and the socket.

Push the three hoses onto the back of the pump and secure them using the clamps and pliers.

Secure the banjo bolt to the front of the new pump with the socket and ratchet.

Reconnect the negative battery cable to the negative battery terminal with the socket and ratchet.
