How to Remove an Electric Fuel Pump

Electric fuel pumps force fuel from the fuel tank through the fuel injection system. In older vehicles, before fuel injection systems, the fuel pump was not electric and the fuel was pumped to a carburetor. In newer cars, electric fuel pumps are located in the gas tank, and their removal can be a tricky operation. There are many safety precautions to take before attempting to remove an electric fuel pump from a vehicle.

Instructions

1

Put the vehicle in park and set the parking brake. Brace both front tires with safety blocks to ensure the vehicle wont move during the repair.

2

Siphon the remaining fuel in the gas tank into a fuel container. The gas tank will need to be nearly empty for this repair. Unscrew the fuel cap on the side of the vehicle and insert a length of hose into the fuel tank. Use a hand pump to start the siphoning action and catch the fuel inside the fuel container.

3

Lift the vehicle by placing two jacks at the back corners of the vehicle, one on each side. Using two jacks will provide more support for the vehicle.

4

Disconnect the filler and vent hoses from the fuel tank. These will be held on with a clamp.

5

Use a socket wrench to remove the bolts that hold the tank to the vehicle on the side that the hose is connected on. Gently lower the fuel tank down a bit. This will allow sufficient space to disconnect all of the wires and connections from the pump to the fuel tank by using wrenches or pliers.

6

Disconnect the other two bolts holding the fuel tank in place. Place the tank on the ground.

7

Remove the fuel pump by releasing the clamps on the pump. Sometimes the pump is also held in place by screw nuts which require a wrench to remove. Extract the fuel pump from the fuel tank and set the pump aside.
