FUEL SYSTEM
Diesel Fuel
Use No. 2 diesel fuel with a cetane rating
of
45
or
higher. Never use kerosene
or
home heating oil since
these fuels
do
not
have the same lubricating properties as
No.2
diesel fuel.
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 Filters
A
primary
fuel
filter
of
the
water
entrapment type must be installed be-
tween the fuel tank and the engine. A
primary
fuel filter, shown here, is
available from
your
local Westerbeke
representative
or
your
boatbuilder.
This filter, adapted
for
boatbuilder
use, comes complete with fittings
for
either hose
or
metal tubing. Mount it
in
an accessible place, inspect it often
and drain off water accumulation fre-
quently.
If a water trap type filter is
not
installed
between the fuel tank and the engine-
mounted fuel system, any water in the
fuel system will tend
to
lay in the bot-
tom
of
the electric lift pump. Internal
metal parts
of
the lift pump will rust.
Particles will pass on
to
filters and
eventually
to
the injection
pump
and
injectors with damaging results and
the possibility
of
expensive repairs.
Remember, water damage
to
the fuel
system is
not
covered

Westerbeke warranty. The owner/operator is responsible in making sure that fuel reaching the engine's in-
jection equipment is free
of impurities. This process is accomplished
by
installing a proper filtration/separa-
tion system and maintaining this system.
In addition, any gasoline in the fuel system will damage the engine's fuel injection pump assembly and in-
jectors, as gasoline does not have the same lubricating qualities as diesel fuel.
Although most boatbuilders supply a water trap/filter, some
do
not. Westerbeke offers a sedimentary/water
trap/filter as an optional extra at moderate cost. The filter is supplied with fittings
for
either hose
or
metal
tubing fuel lines.
