FUEL
SYSTEM
Diesel Fuel
Use
No.2
diesel fuel with a cetane rating
of
45.
Never
use kerosene
or
home heating oil.
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
between the fuel tank and the en-
gine.
Such a filter, shown here, is
available from
your
local Wester-
beke representative
or
your boat-
builder. This filter, adapted
for
the
boatbuilder's 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 frequently.
If a water trap type filter is not in-
stalled between 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 injec-
tion pump and injectors with damag-
ing results and the possibility
of
expensive repairs. Remember, water
damage
to
the engine's fuel system
is not covered under the Westerbeke warranty.
Although most boatbuilders supply a water trap/filter, some
do
not. Westerbeke offers a sedimenter/water
trap/filter as an optional extra at moderate cost. The filter is supplied with fittings for either hose
or
metal'
tubing fuel lines.
Generator models covered
by
this manual have
two
replaceable fuel filters in the engine-mounted fuel sys-
tem.
One is in the base
of
the electric fuel pump and the other in the filter assembly located just after the dis-
charge side
of
the electric fuel pump.
The self-bleeding feature
of
the fuel system allows for easy servicing
of
the filters. Simply remove and replace
the filter elements. (Take care
to
catch any fuel when removing these filter elements.) Energize the PREHEAT
switch and allow the electric fuel pump
to
operate for 20 - 30 seconds
to
prime and bleed air from the sys-
tem. (No fittings should
be opened.) Then proceed
to
start the engine as you normally would. If the engine
fails
to
start, stop and wait a few moments, and then repeat the bleed procedure as indicated above.
