Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal from the battery to ensure safety.
Raise the vehicle securely on jack stands if accessing the fuel tank from underneath.

2. Inspect and Repair the Fuel Sender Unit

Access the Fuel Tank:
- Remove the rear seat cushion if the fuel sender is accessible from inside the cabin, or access from beneath the vehicle if necessary.
- Remove any protective covers as required.
Remove the Fuel Sender:
- Disconnect the wiring harness from the fuel sender unit.
- Unscrew the retaining ring or bolts securing the fuel sender to the tank and lift it out carefully.
Inspect the Fuel Sender:
- Check the float arm for any obstructions or damage.
- Use a multimeter to measure resistance (should vary as the float moves).
- If defective, replace with a new fuel sender unit.
Reinstall the Fuel Sender:
- Position the new or repaired fuel sender unit into the tank.
- Secure it with the retaining ring or bolts, and reconnect the wiring harness.

3. Reassemble and Test the System

Reassemble Components:
- Replace any covers or seats that were removed during access.
- Ensure all connectors are firmly attached.
Reconnect the Battery:
- Reattach the negative battery terminal and ensure it is tight.
Final Testing:
- Start the vehicle and verify that the fuel gauge operates correctly.
- Test drive the vehicle to confirm the gauge reflects the accurate fuel level.
