2009 Chevrolet Impala Fuel Level Sensor Parts Questions & Experts Answers

• Q: How to replace the Fuel Level Sensor in the fuel sender assembly (RPO NU6) on 2009 Chevrolet Impala?

  A: The first step for Fuel Level Sensor replacement requires tank fuel removal. Take evap lines and fuel feed out of their positions to reach the lock ring through the sensor openings. The j 45722 (Fuel Level Sensor Lock Ring Wrench) must be employed for unfastening the Fuel Level Sensor lock ring in a counterclockwise motion while you maintain the lock ring and Fuel Level Sensor free of contact with fuel pipes. Lock ring removal requires significant force that makes hammer-screwdriver methods unacceptable. Professionals must only utilize the j 45722 (Fuel Level Sensor Lock Ring Wrench) tool to unlock the lock ring in a counterclockwise direction. Insert the securement tool to keep the Fuel Tank from rotating. Dispose of the Fuel Level Sensor o-ring seal and devote time to cleaning the surfaces that require sealing. The lock ring requires two inspections for both damage and flatness measurements. Replacement is mandatory when measuring warpage reaches greater than 0.41 mm (0.016 in). End up by installing a new o-ring Fuel Level Sensor seal onto the Fuel Tank before you set the Fuel Level Sensor into position in the correct alignment tab placement and then position the lock ring on the tank. Installation of the Fuel Level Sensor requires a new Fuel Level Sensor seal along with correct assembly of the lock ring by facing its upward position and turning it clockwise using j 45722. The last procedure involves connecting the needed lines onto the sensor after which you can safely reinstall the Fuel Tank.
