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.

The fuel transfer pump is integral with the governor. Fuel is sent from the fuel transfer pump through the pressure relief valve (10). The pressure relief valve is closed in normal operation. Fuel will enter through fuel filter (9) to a drilled passage in the cylinder head (6). Once the pressure of the fuel is greater than the desired range then the pressure relief valve will open. This will allow the fuel to return to the tank. 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.

Fuel transfer pump (A) Inlet flow of fuel (B) Outlet flow of fuel (1) Screen (if equipped) (2) Inlet check valve (3) Spring (4) Piston assembly (5) Outlet check valve (6) Piston check valve (7) Tappet assembly (8) camshaft (9) PassageThe fuel transfer pump is located in the front housing of the governor. The pump is activated by camshaft (8) that is attached to the shaft of the governor drive gear. Piston assembly (4) and tappet assembly (7) are stroked up and down by the camshaft and spring (3) .Fuel enters the transfer pump through screen (1) (if equipped) and inlet check valve (2). On the upstroke of piston assembly (4), check valve (2) closes. Outlet check valve (5) closes in order to prevent fuel from being pulled back in the pump from the outlet. As pressure increases above piston assembly (4), piston check valve (6) opens in order to fill the cavity above the piston assembly.On the downstroke, as the fuel pressure in passage (9) increases, piston check valve (6) is closed and outlet check valve (5) is opened. This causes fuel to be pushed through the secondary fuel filter and to the engine. Inlet check valve (2) opens in order to allo
