Disconnect the electrical connector from the fuel pump.
Carefully detach the fuel lines, using a line removal tool if necessary to avoid damage.
Remove the retaining ring or screws securing the fuel pump assembly to the fuel tank.
Lift the fuel pump assembly out of the tank, being cautious of any residual fuel.

4. Install the New Fuel Pump

Place the new fuel pump into the assembly, ensuring it is oriented correctly.
Reattach the retaining ring or screws to secure the fuel pump assembly in place.
Reconnect the fuel lines and electrical connector, ensuring they are secure and leak-free.

5. Reassemble and Test

Replace the access panel and secure it with screws.
Reinstall the rear seat cushion.
Reconnect the battery and install the fuel pump fuse.
Turn the ignition key to the "ON" position to prime the fuel system, then attempt to start the engine.
