a.
Fuel to power the engine is pumped out of the fuel tank by an engine-mounted fuel injector pump.
b.
The engine fuel system consists of one fuel injector pump, one injector per cylinder, fuel lines, a primary fuel filter,
and a fuel filter/water separator.
c.
The engine is governed by fuel injector pump built-in governor. The system controls idle speed and limits engine
maximum speed. The driver controls engine speed through the position of the foot pedal assembly.
d.
Fuel filters are spin-on types. The primary fuel filter has a water drain. The fuel filter/water separator has a hand
fuel primer pump and a water drain.
e.
Fuel may be drained from the tank through the drain port located on the bottom of the tank.
f.
There is an ether quick-start system for use in cold weather. It is manually controlled via a pushbutton on the
instrument panel in the cab.
