Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Allow the vehicle to cool down before working on the fuel system.

2. Access Fuel Sender Unit

Tools Required: Socket set, flathead screwdriver, safety glasses, fuel line disconnect tool.
Remove the rear seat or access panel to reach the fuel pump assembly.
Disconnect the battery terminal.
Carefully remove any fasteners securing the fuel pump access cover and take off the cover.

3. Inspect and Test Fuel Sender

Tools Required: Multimeter.
Disconnect the electrical connector from the fuel sender unit.
Using a multimeter, measure the resistance across the sender terminals. It should vary as the float moves.
If the resistance is stuck or out of specification, the fuel sender unit may need replacement.

4. Replace Fuel Sender Unit

Tools Required: Socket set, new fuel sender unit, fuel line disconnect tool.
Remove the fuel sender unit from the tank by unscrewing the retaining ring and carefully lifting it out.
Install the new fuel sender unit, ensuring the float moves freely.
Reassemble the access cover and secure it with fasteners.

5. Reconnect Battery and Test

Reconnect the battery terminal.
Turn on the ignition and check if the fuel gauge operates correctly.
Test drive the vehicle to ensure the fuel gauge provides accurate readings under different fuel levels.
