Fuel for generator set operation is supplied from either the integral main fuel tank or an auxiliary source as determined by the fuel selector valve. Fuel is pumped through the strainer and filter assembly and fuel solenoid valve into the day tank by two electrically driven fuel transfer pumps. The day tank fuel level and low fuel cutoff switch controls the operation of the fuel transfer pumps and the fuel solenoid valve. Fuel from the day tank is drawn through the secondary fuel filter assembly by the fuel injection pump. This single cylinder, opposed plunger, inlet metering type pump forces a metered amount of fuel under high pressure and in timed sequence to the fuel injection nozzle holders in the engine cylinder head. The nozzle holders spray a metered amount of fuel into each combustion chamber. Unused fuel is returned to the day tank through the fuel return line. 3-39 c. Rebuild. If the wiring harness has sustained damage and requires repair or rebuild, refer to figure 3-17 for
