Duramax Fuel Pressure Release Wrench, No. 14400

The SP Tools Duramax Fuel Pressure Release Wrench, No. 14400, features a two-piece design to remove the fuel rail pressure release valve sensor on 2011 and later Duramax LML engines. The design provides the tool versatility needed to access the valve. The technician only needs to unbolt the AC compressor and front EGR valve to access the fuel pressure release valve, eliminating the need to remove the EGR cooler and fuel rail in the process.
