How to Install a Fuel Pump on a 2002 WRX Wagon

The Subaru Impreza WRX is an all-wheel vehicle available as a wagon or sedan. Subaru has manufactured the Impreza WRX since 1992 and completely updated this vehicle line in 2002. The 2002 WRX wagon has a turbocharged 2.0-liter engine with sequential fuel injection, requiring a high-pressure fuel system. The fuel pump in this vehicle is accessible from the rear passenger compartment. The installation of a new fuel pump in a 2002 WRX wagon also requires you to relieve the fuel system pressure and drain the fuel tank.

Instructions

1

Remove the rear seat cushion to expose the access cover for the fuel pump. Disconnect the mounting bolts for the access cover with a socket wrench and remove the access cover. Detach the electrical harness from the fuel pump and start the engine. Allow the engine to stall and crank it again for at least five seconds to ensure that the fuel system is empty.

2

Disconnect the cable on the negative battery terminal with a socket wrench. Raise the vehicle with a jack and support it on jack stands. Place a gasoline container under the drain on the fuel tank and remove the front cover for the fuel tank. Remove the drain plug for the fuel tank and drain the fuel into the container.

3

Fasten the drain plug and tighten it to between 14 and 24 pound-feet with a socket wrench. Replace the front cover for the fuel tank and and torque its retainers to between 9.4 and 16.6 pound-feet.

4

Detach the fuel lines from the fuel pump and remove the mounting nuts for the fuel pump with a socket wrench. Pull the fuel pump assembly from the fuel tank and discard the gasket.

5

Place the new gasket into the mounting groove on the fuel tank and install the new fuel pump assembly. Tighten the mounting nuts for the fuel pump assembly to 3 pound-feet with a torque wrench.

6

Connect the electrical harness and fuel lines to the fuel pump assembly and lower the vehicle. Replace the fuel pump cover and fasten the mounting bolts with a socket wrench. Replace the rear seat cushion and connect the negative battery terminal. Start the engine and check the fuel system for leaks.
