Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Remove Fuel Pump Assembly

Tools Required: Fuel line disconnect tool, socket set, torque wrench.
Locate the access panel for the fuel pump (usually in the trunk or under the rear seat).
Remove the access panel and disconnect the electrical connector from the fuel pump assembly.
Use a fuel line disconnect tool to carefully detach the fuel lines from the pump.
Unscrew the retaining ring using a socket set and lift the fuel pump assembly out of the tank.

3. Inspect and Replace Fuel Level Sensor

Check the fuel level sensor attached to the fuel pump assembly for any visible damage.
If damaged, replace the fuel level sensor by carefully detaching it from the assembly.
Install the new fuel level sensor and ensure it is secured properly.

4. Reinstall Fuel Pump Assembly

Place the fuel pump assembly back into the tank and secure it with the retaining ring.
Reconnect the fuel lines and electrical connector to the pump.
Replace the access panel and ensure everything is secured.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the vehicle and check the fuel gauge for proper functionality.
Test drive the vehicle to ensure the gauge reflects accurate fuel levels during operation.
