TM 5-3805-261-20PRINCIPLES OF OPERATION. (cont)1-15.FUEL SYSTEM. (cont)f.FuelInjectorPump. Fuel from primary fuel filter flows to gear driven fuel injection pump. Fuel is againfiltered, then metered accurately and applied to each cylinder at high pressure throughfuel injector nozzles. The fuel isdelivered at precisely timed intervals.The throttle control lever controls fuel metering through a cable connection. This also attaches to an accelerator pedal.The centrifugal speed regulating governor is located within the fuel injector pump housing.g.FuelFilters. Primary filter is mounted on the fuel tank. Secondary filter is mounted on the fuel injector pumphousing. Primary and secondary fuel filters remove fuel oil impurities which may damage the fuel injector pump and/ornozzles.h.FuelStrainer(Figure 1-8). Located in fuel tank fill opening. Prevents passage of foreign material into thefuel tank.Figure 1-8.i.EtherAidColdStartKit(Figure 1-9). The ether starting aid bottle and operator controlled electric activatorare mounted on rear surface of fuel tank toward the right side of the vehicle. Ether is injected through a tube attached tothe intake manifold. Temperature sensitive automatic closure switch mounted on water pump prevents ether aid useabove 32 degrees F.Figure 1-91-24
