The fuel transfer pump is integral with the governor. Fuel is sent from the fuel transfer pump through fuel filter (5) to a drilled passage in the cylinder head (6). The drilled passage in the cylinder head intersects a gallery around each unit injector in order to provide a continuous flow of fuel to all injectors.When there is air on the inlet side of the fuel system, fuel priming pump (A) (if equipped) may be used in order to fill the fuel filter and the fuel gallery that is in the cylinder head. This is performed before the engine is started. When the priming pump is used, check valves that are located in the fuel priming pump control the movement of the fuel. The fuel is forced through the low pressure side of the fuel system. This removes air from the fuel lines and components back into the fuel tank.
