Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Access Fuel Pump

Remove the rear seat or access panel to reach the fuel pump assembly.
Disconnect any electrical connectors and fuel lines carefully, using appropriate tools to avoid damage.

3. Remove Fuel Pump Assembly

Unscrew the retaining ring or bolts securing the pump assembly in place.
Carefully lift out the fuel pump module from the fuel tank, ensuring no fuel spillage.

4. Inspect and Replace

Inspect the fuel pump for any visible signs of damage or wear.
If necessary, replace the fuel pump with a new unit, ensuring it is compatible with the Volvo XC60 specifications.
Install a new fuel filter if clogged or damaged.

5. Reassemble

Reinstall the fuel pump assembly into the fuel tank.
Secure with the retaining ring or bolts.
Reconnect the fuel lines and electrical connectors.

6. Final Checks

Reconnect the battery and turn the ignition to the "ON" position without starting the engine to prime the fuel system.
Check for leaks around the fuel pump and lines.
