Fuel System; Fuel Lift Pump - Westerbeke 8.0KW-60HZ Operator's Manual

FUEL SYSTEM
GASOLINE
Use
unleaded
89 octane or higher gasoline. When fueling,
follow U.S. Coast Guard regulations, close off all hatches and
companionways to prevent fumes from entering the boat, and
ventilate after fueling.
NOTE:
The engine compartment should have a gasoline fume
detector/alarm properly installed and working.
GASOLINE/WATER SEPARATOR AND FILTER
A primary fuel filter of the water separating type must be
installed between the fuel tank and the engine to remove
water and other contaminants from the fuel before they can
be carried to the fuel system on the engine.
Most installers include a type of filter/water separator with
the installation package as they are well aware of the problems
that contaminants in the fuel can cause.
These gasoline filters must have metal bowls (not "see-
through") to meet U.S. Coast Guard requirements. The metal
bowls have drain valves to use when checking for water and
impurities. .

AWARNING:
Shut off the fuel valve at the tank when
servicing the fuel system. Take care in catching any fuel
that may spill. 00 NOT allow any smoking, open flames or
other sources of fire near the fuel system when servicing.
Ensure proper ventilation exists when servicing the fuel
system.
CARBURETOR
The carburetor is a single barrel downdraft type with an electric
solenoid operated choke. Refer to CARBURETOR
ADJUSTMENTS for more information.
FUEL LIFT PUMP
Periodically check the fuel connections to and out of the pump
and make sure that no leakage is present and that the fittings
are tight and secure. The DC ground connection at one of the
pump's mounting bolts should
be
clean and well secured by
the mounting bolt to ensure proper pump operation.
A WARNING:
Fuel leakage at the fuel pump or its
connections is
a
fire hazard and should be corrected.
Make sure proper ventilation exists whenever servicing
fuel system components.
The start sequence energizes the fuel lift pump as the piston in
the pump operates, it creates an audible ticking sound. If no
ticking is heard, check for 12 volts at the pump connections.
Also check that the ground wire is properly connected to the
ground.
GASDENSER
The gasdenser cools the fuel to prevent vapor lock. There is
no maintenance required except making certain the fuel
fittings are tight and secure.
