Many fuel pumps are often used on similar engines. In order to identify the correct fuel pump for your application, it is necessary to determine the position of the inlet, outlet and separator fitting (where applicable) in relation to the rocker arm. The angle between the rocker arm and the fuel inlet is expressed in terms of clock position. Place pump with rocker arm in the 12 o’clock position. The rocker arm must be held behind the fuel pump body. (The bottom of the fuel pump body must face you.) Observe the relationship of the fuel inlet to the rocker arm. This position is the clock position of the pump. Examples of this in the outline drawing below show that if the fuel inlet is at position "A", it is considered a 6 o’clock pump, if at position "B". a 3 o’clock pump, and at position "C" an 8 o’clock pump.
