5. Replace the Fuel Sensor
Check the old fuel sender unit for any damage or deterioration. If you notice defects or improper sensor readings, replace it with a new fuel sender unit.
6. Reinstall the Fuel Sender Unit
Put the new or repaired fuel sender unit into the fuel tank. Ensure that the rubber gasket is properly seated and the unit fits securely.

Important Notes
- Before starting work, make sure to engage the parking brake and allow the engine to cool down completely to avoid burns.
- If you're not comfortable working with fuel system components, it's best to have the fuel sensor replaced by a professional mechanic.
