A gear pump is provided within the pump housing which is operatively associated with the drive shaft of a starter motor. A shaft extension device is also provided which may be adapted to a starter motor drive shaft thereby allowing the device of the present invention to be used with a variety of starter motors. The pump assembly is provided with a fluid delivery system which is operatively associated with the fluid inlet means in the pump housing. Further provided is a receiver means which receives fluid discharged from the outlet means of the pump housing. A pressure regulating device may also be provided within the end cap of the pump housing. The pressure regulating device is operatively associated with the pump assembly and controls fluid pressure in the pump fluid cavity during operation of the pump assembly.
