The fuel pump on a 2000 Ford F-250 with the 7.3L diesel engine is responsible for getting fuel to the engine. When the fuel pump goes out, the engine won't get the proper amount of fuel at the correct pressure. As a result, the engine cannot run properly. Fortunately, fixing this problem doesn't require taking apart the gas tank--just an hour of your time under the hood.

Tools Used[edit]

Jack stands
Needle-nose pliers
Ford fuel line removal tool
3/8-inch ratchet and socket set

Replace a Fuel Pump[edit]

  • Open the gas door and remove the gas cap with your hands. Locate the fuel pump on the rear side of the engine. Lift up the front of the Ford using the jack and put the F-250 on jack stands so that you can get better access to the pump and fittings.
  • Unplug the electrical connection to the fuel pump. Take off the fuel line retaining clip using the needle-nose pliers and disconnect the fuel line by hand. Remove the clip on the fuel pump delivery line using the needle-nose pliers, then remove the fuel line using the Ford fuel line disconnect tool.
  • Unbolt the fuel pump bracket using the 3/8-inch ratchet and socket. Remove the brake lines from the bracket, then remove the fuel pump from the engine.
  • Mount the replacement fuel pump in the bracket using the 3/8-inch ratchet and socket. Reconnect the fuel lines and clips by hand as well as with the needle-nose pliers. Plug the fuel pump harness back into the fuel pump by hand. Reinstall the gas camp and close the gas door.

Tips & Warnings[edit]

  • Never smoke or have an open flame nearby while you're working on the fuel system of a vehicle. If you do, you risk starting a fire and causing damage to yourself and the vehicle.
