Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove the Fuel Sender Unit

Locate the fuel sender unit, typically found on or near the fuel tank.
Remove the access panel if applicable (may require socket set).
Disconnect the electrical connector from the fuel sender unit.
Unscrew the retaining ring using a special tool or hammer and a flathead screwdriver.
Carefully lift the fuel sender unit out of the tank, taking care not to damage the float arm.

3. Inspect and Repair

Check the float arm for any signs of corrosion or damage; replace if faulty.
Test the resistance of the fuel sender unit with a multimeter; it should change as the float moves.
Clean any corrosion from the electrical connectors and check for continuity in the wiring.
If the sender unit is defective, replace it with a new unit.

4. Reassemble Components

Carefully insert the fuel sender unit back into the tank.
Secure it with the retaining ring, ensuring it is tight but not over-tightened.
Reconnect the electrical connector.
Reinstall the access panel if applicable.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and observe the fuel gauge to ensure it operates correctly.
Perform a test drive to verify the accuracy of the fuel gauge readings.
