How Does It Work?
Step 1 – Close The Gas and Power Lines
- Remove negative battery cable. Raise the rear hatch or open the trunk and take out the spare tire if you have one. Detach gas as well as electric power cables to the fuel tank.
Step 2 – Detach The Tank
- Unclip the electrical cables using a pair of small screwdrivers, and remove the tank holders. Take out three bolts on the bearers that support the tank under the vehicle as well. Then, gradually move vehicle's gas tankdown (a smaller amount of gasoline makes the tank lighter to hold). You can ask a friend to help you to hold the tank, with each person on either end.
Step 3 – Remove Transmitting Device
- Remove the clips on the electrical attachment at the top of transmitting device (you should not detach the gas pipe at this time because fuel will come out from the tank). Next, using a screwdriver and hammer, rotate the lock ring at the top of the transmitting device to line up the lock tabs and channels. Spray the lock ring with lubricating oil w...
Step 4 - Remove Fuel Level Sensor
- Locate the fuel level sensor, which is often situated on the very bottom part of the transmitting device. Remove the clip from the harness and slide off the sensor.
Step 5 – Fit New Sensor
- When you purchase a new fuel level sensor, be sure to consult with your vehicle's owner's manual, or with a store associate, to make sure you're buying the right part.
