Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if it has been running.

2. Remove the Fuel Sender Unit

Tools Required: Socket set, screwdrivers, safety glasses, gloves.
Locate the access panel for the fuel sender unit, usually found beneath the rear seat or trunk.
Remove the access panel using a screwdriver or socket set.
Disconnect the electrical connector from the fuel sender unit.
Unscrew the retaining ring and carefully lift out the fuel sender unit from the tank.

3. Inspect and Test the Fuel Sender Unit

Check the float arm for any obstructions or damage.
Using a multimeter, measure the resistance of the fuel sender unit as you move the float up and down; it should vary smoothly within manufacturer specifications.
If the readings are outside the specified range, replace the fuel sender unit.

4. Reinstall the Fuel Sender Unit

If the fuel sender unit is in good condition or after replacement:
- Ensure the O-ring is in place and clean.
- Carefully insert the fuel sender unit back into the tank.
- Secure it with the retaining ring and reconnect the electrical connector.
- Replace the access panel.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe the fuel gauge.
Conduct a test drive to ensure the fuel gauge reflects accurate readings during various fuel levels.
