  Q: How to replace the Fuel Level Sensor in the fuel sender assembly on Chevrolet Silverado 3500 Classic?

  A:

  The necessary tool for replacing the Fuel Level Sensor assembly is the Fuel Level Sensor lock ring wrench (J 45722). The first step requires tank fuel removal followed by disconnecting the lines from both the Fuel Level Sensor and evaporative emissions (EVAP). The Fuel Level Sensor assembly must have its fuel drained into an approved container through proper procedures since open fuel storage poses risks of fire and causes personal injuries. The proper tool for this operation is the Fuel Level Sensor lock ring wrench (J 45722) since it prevents lock ring damage. Handling the Fuel Level Sensor assembly through its fuel pipes will lead to joint damage. The correct tool for unlocking the Fuel Level Sensor lock ring is the Fuel Level Sensor lock ring wrench (J 45722) which requires a long breaker-bar for the operation. The Fuel Level Sensor should be removed while discarding the seal for surface cleaning of the unit's sealing sections. The counterclockwise rotation of the Fuel Level Sensor lock ring needs inspection for damage between checking for its flat surface. Replacement of the lock ring becomes mandatory when its warpage exceeds 0.41 mm (0.016 in). The horizontal position of the fuel strainer should be maintained while installing the Fuel Level Sensor to allow the float arm to move freely during operation. The installation of new Fuel Level Sensor seals and the lock ring procedure requires correct placement of the lock ring with proper upward orientation while maintaining clockwise turning only. The Fuel Level Sensor lock ring wrench (J 45722) enables users to lock down the ring secure. Next, install the evap line and fuel line to the Fuel Level Sensor before mounting the Fuel Tank.
