Ensure the vehicle is on a flat surface and securely lifted if needed.

2. Remove Fuel Pump Assembly

Sub-steps:
- Remove the rear seat or access panel to expose the fuel pump assembly.
- Disconnect the electrical connector from the fuel pump.
- Carefully unclip or unbolt the fuel pump assembly from the tank.
- Lift the assembly out of the tank, taking care not to damage the fuel lines.
Tools Required:
- Socket set
- Screwdriver set
- Pliers

3. Inspect and Replace Fuel Level Sending Unit

Sub-steps:
- Locate the fuel level sending unit within the fuel pump assembly.
- Inspect for corrosion, damage, or wear on the sending unit.
- If damaged, replace the sending unit with a new one.
- Reassemble the fuel pump assembly with the new sending unit.
Tools Required:
- Torque wrench (for reassembly)

4. Reinstall Fuel Pump Assembly

Sub-steps:
- Carefully reinstall the fuel pump assembly back into the fuel tank.
- Reconnect the electrical connector to the fuel pump.
- Secure the assembly in place with clips or bolts.
- Reinstall the rear seat or access panel.

5. Final Steps

Reconnect the battery.
Turn on the ignition to the "On" position without starting the engine to allow the fuel system to prime, then check if the fuel gauge operates correctly.
