The 6BT Injector Return Screw with Washer (3905307-AAFT) is a critical component in the fuel injection system of Cummins 6BT diesel engines. This screw, along with its washer, seals and secures the connection between the injector and the fuel return line. Its primary function is to ensure efficient return of excess fuel from the injector back to the tank, preventing leaks and maintaining optimal engine performance. A malfunctioning screw can lead to fuel leaks, decreased engine power, increased fuel consumption, and, in severe cases, damage to the injection system. Regular preventative maintenance, including inspection and replacement of the screw and washer if worn or damaged, is crucial to prevent these issues. We recommend professional installation by a qualified technician to ensure correct fitting and optimal functionality.
