PUMP
Periodically check the fuel connections to and out of the pump
and make sure that no leakeage 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.
The engine mounted fuel lift pump is maintenance free. It is
located at the front of the engine under the 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.
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 generator installation package as they are well aware of
the problems that contaminants in the fuel cim cause.
These gasoline filters must have
metal
bowls (not "see-
through") to meet U.S. Coast Guard requirements. The metal
~?owls
have drain valves to use when checking for water and
impurities.
