FUEL SYSTEM
Diesel
Fuel
Use No. 2 diesel fuel with a cetane rating
of
45
or
higher. Never use kerosene
or
home heat-
ing
01.
.
In
cold weather particularly, water vapor
is
produced
by
condensation when air
is
present
In
the
fuel tank. Keep fuel tank(s) full and completely free
of
dirt
and water.
Fuel FUterWater Separators
A
primary
fuel
liter
of
the water separating type
l1llm!
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
insIaIIers
included
with the gen-
erator insIaIIaIion package a type of
fIter/Water
separator
for
they
are
aware
of
the probeIms contaminants In the
fuel
can
cause
- all of which
are
not
warrantable through Westerbeke.
A typical fuel filter/Water separator is
IIUSIrated
In this diagram. This is the
Raycor
Model
SOOMA.
~
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 fuel
reaching
the
engine's injection equip-
ment is free
of
impuritieis. This
process
is
accomplished
by
intstalling
and
maintaining a proper filtration/separa-
tion system.
In addition,
any
gasoline in the fuel
system
will
damage the engine's fuel
injection pump assembly
and injectors
as gasoline does not have the same
lubricaticg qualities as diesel
fuel.
Fuel Filter/Water Separator
If a filter/Water separator
is
not installed between the fuel tank and the engine-mounted fuel
system, water in the fuel system
wl1l
inhibit proper starts and particles will pass on
to
the
lift
pump's filter, eventually clogging it and pass on into the engine's injection equipment.
Notes
on
Fuel
System
iWARNINGI
Shut
off
the
fuel service valve
althe
tank when servicing the fuel system. Take care
in
catching
any fuel that may
spDi
from within the pump when the base
is
removed. DO NOT allow any
smoking, open flames,
or
other sources
of
fire near the fuel system when servicing. Ensure
proper ventDiation exists when serviCing the
fuel
system.
