A replacement of fuel supply lines, fuel filters, fuel injection pump, high pressure fuel lines and injectors will let air enter the fuel system. Air in the fuel system will make the engine hard to start, run rough, misfire, and produce low power and cause excessive smoke and fuel knock. Replacing procedure of Air filter, Fuel filter of Generator: Replacing the fuel supply lines, fuel filters, fuel injection pump, high presser fuel lines and injectors will let air enter into the fuel system. One must follow the system to bleed the air from the system. Since the fuel transfer pump provides positive pressure through the fuel filter and supply line to the fuel injection pump, loose connections or defective seals show as a fuel leak and not as an air leak. For faster air purge small amounts of air can be bled from the fuel injection pump by operating the hand primer located on the fuel transfer pump or by cranking the engine. O

What will bad Impact if Air in Fuel of Generator? Air in Fuel  Fuel is flammable. Keep all cigarettes, flames, pilot lights, arcing equipment and switches out to the work area and areas sharing ventilation to reduce the possibility of severe personal injury or death when working on the fuel system. Do not vent the fuel system on a hot engine this can cause to spill onto a hot exhaust manifold which can cause a fire.   How to bubble test of diesel generator fuel? The low pressure fuel system for diesel generator installation in the vehicle consists of the fuel tank lines between the tank and the engine transfer pump and lines and fuel filter and lines. Air or bubbles at the injection pump can cause the engine not to operate or erratic engine operation and subsequent  malfunction of the injection pump. Air can be introduced by leaks in the fuel system prior to transfer pump since the fuel in the lines in under a vacuum and can draw air into the system.
