A compressor wheel on the opposite end of the turbine wheel shaft rotates and draws in
fresh air through the air cleaner (1), compresses the air, and delivers it to the engine blower
(3).
Air from the engine blower (3) flows through the aftercooler (4) which cools the air before it
is delivered to the engine cylinders.
FUEL SYSTEM

The fuel passes through primary filter/water separator (3).
The fuel passes into the fuel transfer pump (1) and the fuel is then pressurized.
The fuel transfer pump (1) incorporates a check valve in order to permit a fuel flow around
the gears for hand priming.
The fuel transfer pump (1) also incorporates a relief valve in order to protect the system
from extreme pressure.
