• Q: How to replace the Fuel Level Sensor in a utility or crew cab on 2005 Chevrolet Blazer?

  A: Tires start by disconnecting the negative Battery Cable in order to replace the Fuel Level Sensor in a utility or crew cab. The first step involves removing the Fuel Tank while using the Fuel Tank sending unit wrench (J 44402) to eliminate the retaining ring of the Fuel Level Sensor. Handling the Fuel Level Sensor by the fuel pipes could result in damage therefore avoid this practice. Take out the Fuel Level Sensor and its seal from the system keeping the old seal for disposal while placing collected fuel in an approved fire-safe container. The Fuel Level Sensor sealing surfaces need cleaning before you install a new seal to the Fuel Tank. The user needs to install a fresh Fuel Level Sensor gasket to avoid having fuel leaks. The fuel strainer needs to be set up horizontally when installed to enable unrestricted float arm motion. The installing procedure requires placing the Fuel Level Sensor inside the Fuel Tank while it is connected with the retaining ring through use of the Fuel Tank sending unit wrench (J 44402). Begin by reinstalling the Fuel Tank then add fuel before closing the fuel filler cap with proper tightening and reattaching the negative Battery Cable. Proceed to check for leaks by first switching on the ignition for two seconds then waiting ten seconds before switching it back on to examine for fuel leaks.
