Optional Fuel Filler
HOSE FITTING
A primary fuel filter of the water entrap-
ment type should be installed between the
fuel tank and the engine. A primary filter,
shown here, is available from your local
Westerbeke 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.
TUBE PIPING
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 inhibit proper starts. In
addition, particles will pass on to the lift
pump's filter, clogging it in time.
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 wtth fittings for either hose or
metal tubing fuel lines.
Replacing Filter Elements
Generator models covered by this manual have two
fuel filter screens. One is in the carburetor (this fil-
ter is referred to as the inlet filter screen).
To remove this filter screen, unscrew the filter plug
and remove the fuel filter screen behind the plug.
Clean the filter screen or replace it with a new one.
Periodically check this filter screen.
