Disconnect the negative battery terminal to prevent electrical shock.

2. Remove Instrument Cluster

Tools Required: Socket set, screwdriver, trim removal tool
Remove the dashboard trim surrounding the instrument cluster using a trim removal tool.
Unscrew the bolts securing the instrument cluster using a socket set.
Carefully pull the instrument cluster out, disconnecting any electrical connectors attached to the back.

3. Replace Fuel Level Sending Unit (if faulty)

Tools Required: Socket set, fuel line disconnect tool, safety goggles
Relieve fuel pressure from the system by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the fuel tank using a fuel line disconnect tool.
Remove the fuel tank access cover (if applicable) or drop the fuel tank to access the sending unit.
Unscrew and remove the fuel level sending unit from the tank.
Install the new sending unit by reversing the removal steps, ensuring all seals are in place.

4. Reassemble Instrument Cluster

Reconnect the electrical connectors to the back of the instrument cluster.
Secure the instrument cluster in place with the bolts and reattach the dashboard trim.
Reconnect the negative battery terminal.

5. Test the Fuel Gauge

Start the vehicle and observe the fuel gauge operation.
Add fuel to ensure the gauge reflects accurate levels.
