Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Access the Fuel Sending Unit

Sub-steps:
1. Remove the rear seat cushion to access the fuel pump cover.
2. Unscrew the fuel pump cover and carefully lift it to expose the fuel pump assembly.
3. Disconnect the electrical connector from the fuel pump and the fuel lines (use caution as fuel may spill).

3. Inspect and Replace the Fuel Sending Unit

Sub-steps:
1. Remove the fuel sending unit from the fuel tank (usually involves lifting a locking ring).
2. Inspect the float arm for damage or obstruction.
3. If necessary, replace the fuel sending unit with a new one.
4. Ensure the new unit is properly installed and the float moves freely.

4. Reassemble and Test

Sub-steps:
1. Reconnect the fuel lines and electrical connectors.
2. Secure the fuel pump cover back in place and reinstall the rear seat.
3. Reconnect the battery and turn on the ignition to test the fuel gauge operation.
