Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the battery to ensure safety during the repair process.

2. Access the Fuel Level Sending Unit

Tools Required: Socket set, screwdriver, and safety goggles.
Remove the rear seat cushion or access panel to gain access to the fuel pump assembly.
Disconnect any electrical connectors and hoses from the fuel pump assembly.

3. Inspect and Replace the Fuel Level Sending Unit

Remove the retaining ring or screws securing the fuel pump module.
Carefully lift the fuel pump assembly out of the tank.
Inspect the fuel level sending unit for any obvious damage or corrosion.
If faulty, replace the fuel level sending unit with a new one, ensuring it matches the original specifications.

4. Reassemble Components

Reinstall the fuel pump module into the tank, securing it with the retaining ring or screws to the manufacturer's torque specifications (typically around 15-20 ft-lbs).
Reconnect any electrical connectors and hoses that were removed.
Reinstall the access panel or rear seat cushion.

5. Reconnect Battery and Test

Reconnect the battery.
Turn the ignition key to the ON position without starting the engine to allow the fuel system to prime.
Check for proper fuel gauge operation and any leaks around the fuel pump assembly.
