How to Change Out a 2005 Toyota Corolla Fuel Pump

The 2005 Toyota Corolla fuel pump has its fuel pump mounted in the fuel tank, much like many other vehicles. There are differences, however, in removing this pump compared to other models. It is possible to replace the pump itself rather than the entire module. The Corolla is also one of several foreign models where you don't have to remove the fuel tank. The pump is accessible from inside the car's rear compartment.

     Remove the four screws on the fuel pump access cover with your screwdriver and remove the cover.
