Related Repair Advice
- Most modern vehicles use an electric fuel pump, which is mounted inside the fuel tank. Some vehicles have an access panel that can be removed to replace the pump without having to remove the fuel tank.
- In-tank fuel pumps are submerged in fuel to help keep them cool. Running out of gas can damage the fuel pump.
- The fuel filter should always be replaced when replacing the fuel pump
- A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
- Gasoline is highly flammable. When replacing the fuel pump, the battery should be disconnected and proper safety procedures followed to avoid fire and personal injury.
