Use
No.2
diesel fucl with a cetane rating
of
45 or higher. Do
not use kerosene
or
home heating fuel.
FUElJWATER
SEPARATOR
A primary fuel filter
of
the water separating type must be
installed between the fuel tank
and
the engine
to
remove
water
and
other
contaminants from the fuel before they can
be carried to the fuel system
on
the engine.
Most installers include a filter/water separator with the instal-
lation package
as
they are aware
of
the problems that conta-
minants
in
the fuel can cause.
A typical fuel
filter/water separator is illustrated below. This
is the Rayeor Model
500
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 equip-
ment.
The
owner/operator is responsible for making certain
the fuel reaching the engine's injection equipment
is
free
of
impurities. This process is accomplished hy installing
.and
maintaining a proper filtration/separation system.

only
adjustments the

Other
types
of
adjustments
or
repairs must be performed by a qualified
