2. Access the Fuel Pump

Remove the rear seat or access panel to reach the fuel pump module (as applicable).
Disconnect the electrical connector from the fuel pump module.
Carefully unclip and remove the fuel lines from the pump, using a line removal tool if necessary.

3. Remove and Inspect the Fuel Pump

Unscrew the retaining screws of the fuel pump module and lift it out of the fuel tank.
Inspect the fuel pump for any physical damage or signs of wear.
Check the fuel strainer for debris and replace if necessary.

4. Install the New Fuel Pump

If the fuel pump is faulty, replace it with a compatible new unit.
Install the new fuel pump into the fuel tank, ensuring it is seated correctly.
Reattach the fuel lines and electrical connector securely.

5. Reassemble and Test
