Remove the screws or clips securing the access panel and carefully lift it off.
Disconnect the fuel lines from the fuel pump assembly using appropriate tools (fuel line disconnect tool may be required).
Disconnect the electrical connector from the fuel pump.

4. Remove the Fuel Pump Assembly

Remove any retaining screws or bolts securing the fuel pump assembly to the fuel tank.
Carefully lift the fuel pump assembly out of the tank, taking care not to damage the fuel gauge sender.

5. Install the New Fuel Pump

Place the new fuel pump into the fuel tank, ensuring proper alignment.
Secure the pump assembly with the retaining screws or bolts, following the manufacturer's torque specifications.
Reconnect the electrical connector and fuel lines to the new pump.

6. Reassemble and Test

Reattach the access panel and secure it with screws or clips.
Reconnect the negative battery terminal.
Turn the ignition to the "ON" position to prime the fuel system, then check for leaks.
Start the engine and ensure it runs smoothly without any issues.
