How to Change a Fuel Pump on a Subaru Impreza

123

The fuel pump on your Subaru Impreza needs little or no service at all. However, years of service wear out internal components, which affect fuel delivery pressure and engine performance. Fortunately, changing your Impreza’s fuel pump is a very simple task following these steps. The procedure applies to the 2004 model, which is very similar to other years.

Tools Used: Tools, Clean shop rags, Wrench set, Ratchet and socket set, New O-ring fuel tank seal

Change a Fuel Pump

Park the vehiclein a safe and level place. Open the hood and start the engine.

Disconnect the fuel pump relay located in the power distribution box or fuse box at the front and to the left (driver’s side) of the engine compartment. Markings on the relay, the inside or top of the distribution box lid should identify the relay.
