DESCRIPnON
Fuel is drawn into the engine's fuel system by the electric
fuel
pump mounted on the generator's drive engine. Fuel
is drawn from the fuel tank through the primary
fuel
filter/water separator through the
fuel
pump, then under
pressure
(6-8
psi) and delivered
to
the secondary
fuel
fi,lter
mounted on the engine. Fuel passes through this filter
to
the
fuel injection pump where the injection pump delivers it
to
the mjectors, The fuel serves three purposes in the system. It
is
used for combustion, lubrication and carries heat away
from the injection equipment through the return back
to
the
fuel
tank where it
is
dissiPated in the cool fuel in the
tank.

RECOMMENDED
A primary fuel filter
of
the water separating type must be
installed between the fuel tank and
the engine
to
remove·
water and other contaminant's from the
fuel
before
they
can
be carried to the
fuel
system on the
~ngine~_
A typical fuel filter/water separator
is
illustrated
below.
This
is
the Raycor Model500 MA.
Keep
in mind that
if
a water
separator
type filter
is
not installed between the
fuel
supply
tank and engine-mounted fuel system, any water in the
fuel
will affect the fuel pump, engine
filter,
and injection
equipment The owner/operator
is responsible for
making
certain the
~1
reaching the engine's injection equipment is
free
of iniplirities.
This
process is accomplished by installing
and maintaining a proper filtration/separation
system.
