Fuel System Schematic(1) Fuel tank.(2) Tank shutoff valve.(3) Fuel injection nozzle.(4) Fuel manifolds.(5) Fuel injection pump housing.(6) Bleed orifice.(7) Fuel inlet line (from secondary filters).(8) Fuel inlet line (from primary filter).(9) Check valve.(10) Fuel transfer pump.(11) Secondary fuel filter.(12) Primary fuel filter.(13) Fuel priming pump.(14) Fuel transfer pump relief valve.There is one fuel injection pump and one fuel injection nozzle for each cylinder. The fuel injection pumps are located in the fuel injection pump housing. The fuel injection nozzles (3) are located in the injection adapter in the cylinder head.When the engine is running, fuel is pulled from the fuel tank through the fuel supply line and primary fuel filter (12) by fuel transfer pump (10). The fuel is then pushed to secondary fuel filters (11), and into the fuel filter housing. A bleed orifice (6) in the fuel filter housing cover vents air in the system through a line back to fuel tank (1). Fuel from the fuel filter housing goes through fuel inlet line (7) to fuel manifolds (4) in fuel injection pump housing (5). The fuel manifolds supply fuel to each fuel injection pump.Individual fuel injection lines carry fuel from the fuel injection pumps to each cylinder. One section line connects between the fuel injection pump and an adapter on the valve cover base. Another section of line on the inside of the valve cover base connects between the adapter and the fuel injection nozzle (3).The fuel filters and priming
