Remove any screws or clips securing the access panel and lift it off.
Disconnect the electrical connector from the fuel pump.
Use the fuel line disconnect tool to detach the fuel lines from the fuel pump assembly.
Unscrew the retaining ring that holds the fuel pump in place and carefully remove the pump assembly from the tank.

3. Inspect and Replace

Inspect the old fuel pump for signs of wear, such as a burnt motor or clogged filter.
If necessary, replace the fuel pump with a new, compatible unit.
Ensure the new pump has the correct part number for your vehicle.
Reinstall the fuel pump assembly into the tank, securing it with the retaining ring.
Reconnect the fuel lines and electrical connector.

4. Reassemble and Test
