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 Fillers
A primary
fuel filter
of
the water entrapment
type must be installed between the
fuel
tank and the engine. A primary fuel filter,
shown here, is available from your local
Westerbeke representative
or
your boat-
builder. This filter, adapted
for
boatbuilder
use, comes complete with fittings for either
hose or metal tubing. Mount
tt
in an acces-
sible place, inspect
tt
often and drain off
water accumulation frequently.
If a water trap type filter
is
not installed be-
tween
the
fuel
tank
and
the
engine-
mounted fuel system, any water in the fuel
system will tend
to
lay in the bottom
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
wtth damaging results and
the
possibility
of
expensive
repairs.
Remember, water damage
to
the fuel sys-
tem
is
not covered under the Westerbeke
warranty.
In addttion, any gasoline in the fuel system

will damage the engine's fuel injection pump assembly and injectors, as gasoline does not have the same
lubricating qualtties 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.
