2. Fuel Pump Removal

1. Relieve Fuel System Pressure:
- Remove the fuel filler cap to relieve pressure.
- Locate the fuel pump fuse and remove it.
- Start the engine and let it run until it stalls, then turn off the ignition.
2. Disconnect Battery:
- Disconnect the negative terminal of the battery to prevent any electrical short.
3. Access the Fuel Pump:
- Depending on the design, access the fuel pump through the fuel tank access panel or by lowering the fuel tank.
4. Remove the Fuel Pump:
- Disconnect the fuel lines from the pump, ensuring to have a container to catch any spilled fuel.
- Unclip and remove the pump assembly from the tank.

3. Inspect and Replace

1. Inspect the Fuel Pump:
- Check for physical damage, wear, or any signs of fuel leaks.
2. Test the Fuel Pump:
- If applicable, connect the pump to a power source and check if it operates correctly.
3. Replace if Necessary:
- If the pump fails the tests, install a new fuel pump. Ensure it is compatible with the 2017-present Volvo XC60.

4. Reassemble

1. Reinstall the Fuel Pump:
- Place the new or inspected pump back into the tank.
- Reconnect the fuel lines securely.
2. Reconnect Battery:
- Reconnect the negative battery terminal.
3. Replace Fuel Pump Fuse:
- Reinsert the fuel pump fuse into the fuse box.

5. Final Steps

1. Check for Leaks:
- Turn on the ignition to pressurize the fuel system and check for any leaks around the pump and connections.
2. Start the Engine:
- Start the engine and let it idle, monitoring for any irregularities.
