• Q: How to Replace the Fuel Level Sensor in the Front Tank on 2006 Chevrolet Avalanche 2500?

  A: The replacement procedure for the front tank Fuel Level Sensor begins with obtaining the required tool which is the fuel sender lock ring wrench (J 45722). The first step requires removing the front Fuel Tank while you disconnect the lines which connect the fuel and evap system to the Fuel Tank module. The j 45722 tool with a long breaker-bar allows users to remove fuel sender lock ring safely while protecting it from damage only through the designated instrument. The process of handling the Fuel Level Sensor should avoid contact with fuel pipes because it threatens joint integrity and you must never use impact tools because releasing the lock ring demands considerable force. Orientation of the Fuel Tank must be prevented throughout this maintenance procedure. Use the provided j 45722 to unlock the Fuel Tank module lock ring before lifting the module for quick connect fitting access to disconnect the vapor line below the module cover for removal. The old Fuel Tank module seal must be discarded while checking the flatness of the lock ring using a feeler gauge at seven points. A lock ring must be replaced if its warpage exceeds 0.41 mm (0.016 in); otherwise, it can stay in service if not damaged. To install the new Fuel Tank module seal you should position the Fuel Tank module partially into the Fuel Tank before reconnection of the vapor line quick connect fitting and completing the module installation. Position the lock ring and lock its place using the j 45722 while rotating clockwise. Align the ring with the proper side facing upward direction. Always use a new fuel sender seal together with avoidance of lubricating substances in the sealing groove. The concluding step includes connecting both fuel and evap lines to the Fuel Tank module before reattaching the front Fuel Tank.
