Removing and replacing the Duramax fuel rail pressure sensor switch is difficult when using standard wrenches and sockets. The sensor is mounted on the right fuel rail under the EGR Cooler. Using conventional wrenches and sockets, a tech needs to remove the EGR cooler and heat shield(s) to gain access to the sensor. This specially designed wrench allows access without removing the EGR cooler and heat shields.
