Fuel Tank. The fuel tank provides containment for the fuel. A fuel strainer and the fuel level gage are contained in the
1.
filler neck of the tank.
2.
Priming Pump. Primer pump is used to prime the fuel system.
3.
Primary Fuel Filter. The primary fuel filter removes larger particles from the fuel before it reaches the transfer pump.
4.
Transfer Pump. The transfer pump pulls fuel from the fuel tank through the primary fuel filter, and pushes it onto the
secondary filter and the injection pump.
5.
Secondary Fuel Filter. The secondary fuel filter removes smaller particles from the fuel before it reaches the injection
pump.
6.
Injection Pump Housing. The injection pump housing contains the fuel injection pumps which send an exact amount
of fuel to the injection nozzles.
7.
Fuel Injection Nozzle. The nozzles turn the stream of fuel into a fine spray which permits good combustion in the cyl-
inders. There is one nozzle for each cylinder, and each nozzle has its own fuel injection pump.
8.
Governor. The governor is attached to the fuel injection pump housing. It controls the amount of fuel needed by the engine
to maintain a desired engine speed. The governor is controlled by the governor control lever in the operator station.
