1. Fuel injection nozzle. 2. Fuel injection lines. 3. Fuel return line. 4. Constant bleed orifice (part of the elbow). 5. Fuel injection pump housing. 6. Fuel priming pump. 7. Check valves. 8. Fuel transfer pump. 9. Fuel tank. 10. Primary fuel filter. 11. Secondary fuel filter. Fuel is pulled from fuel tank (9) through primary fuel filter (10) by fuel transfer pump (8). From the fuel transfer pump the fuel is pushed through secondary fuel filter (11) and to the fuel manifold in fuel injection pump housing (5). Fuel pressure in the fuel manifold is determined by the fuel transfer pump spring. A constant bleed orifice is in the fuel return line elbow. Constant bleed orifice (4) lets a constant flow of fuel go through fuel return line (3) back to fuel tank (9). This helps keep the fuel cool and free of air. The individual fuel injection pumps get fuel from the fuel manifold and push fuel at a very high pressure through fuel lines (2) to fuel injection nozzles (1). Each fuel injection nozzle has very small holes in the tip that change the flow of fuel to a very fine spray that gives good fuel combustion in the cylinder.
