Examination
1. Release the pressure in the system. Disconnect the negative battery cable.
2. Remove the fuel pump assembly.
3. Disconnect the sensor wire and connect an ohmmeter to pins 2 and 3. Measure the resistance of the sensor when the meter arm is fully down (tank is empty) approximately 110-115 ohms and when the lever is fully raised (tank full) approximately 2-3 ohms. When moving the lever, the resistance should change evenly.
4. Replace sensor if necessary.
Replacement
1. Remove the screws (indicated by arrows) and press tab A and pull the sensor up to remove it.
2. Install a new sensor.
