4. Unscrew the fuel pump assembly retaining ring using a suitable tool.
5. Lift out the fuel pump assembly from the tank.

3. Inspect and Replace

Sub-steps:
1. Inspect the fuel pump for any visible damage or wear.
2. Check the fuel filter and replace it if necessary.
3. If the pump is faulty, install a new fuel pump and ensure all O-rings are seated properly.
4. Reassemble the fuel pump assembly in reverse order of removal, making sure to secure the retaining ring properly.

4. Reconnect and Test

Sub-steps:
1. Reconnect the fuel lines and electrical connectors to the fuel pump.
2. Reinstall the rear seat or trunk panel.
3. Reconnect the negative battery terminal.
