FUEL SYSTEM
FUEL FEED PUMP STRAINER
An additional fuel screen is located in the feed pump. This
screen (strainer)
is removed for cleaning by releasing the
banjo bolt at the bottom. This screen should be cleaned every
250 operating hours. Use compressed air and/or clean with
kerosene.

After changing the fuel filter and cleaning the fuel feed pump
strainer, WESTERBEKE
recommends the following proce-
dure for ensuring there is no air trapped in the fuel system.
BLEEDING (PRIMING) THE FUEL SYSTEM
1. Loosen the bleeding screw on the fuel injection pump.
2. Tum the feed pump knob counterclockwise until the pump
knob
is forced up by the spring.
3. Depressing the
pump knob will cause it to drain out the air
mixed fuel from the loosened bleeding screws.
4. Repeat the pumping action until no bubbles are visible
in
the flowing fuel.
5. Tighten the bleed screw and the feed pump knob.
FUEL ADDITIVES
If fungus or bacteria is causing fuel problems, you should have
an authorized dealer correct these problems. Then use a diesel
fuel biocide
to sterilize the fuel (follow the manufacturer's
instructions ).
SPARE PARTS
While the likelihood of having to service the system at sea is
slim, the possibility does exist. Therefore, we recommend that
banjo washers, injector seat washers and a fuel filter be carried on
board at all times. Purchase needed spare parts from your local
WESTERBEKE dealer or distributor.
If a leak should develop at
a banjo washer that cannot be corrected by a simple tightening of
the fitting, replace the sealing washer with a replacement found in
the hardware kit for your model.
