under certain vehicle operating conditions, the governor weight retainer in the injection pump may fail. the throttle valve could stick, preventing return to idle and shut down of the engine by the driver.
the fuel filters were produced with an incorrect threaded fitting. the incorrect fitting is similiar enough in size that the fuel filter may appear to be correctly threaded onto the fuel line.
