Periodically check the fuel connections to and out of the pump

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
mo~ting
bolt to ensure proper pump operation.
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 checkthat the ground
wire
is properly connected to
ground.
NOTE: At initial start-up or when re-commissioning the engine,
it maybe necessary to prime the engine's fuel system. To
do
this
depress and hold the ON switch. This will activate the engine's
electric fuel pump which will pump fuel through the engine's
fuel system and fill the carburetor's fuel bowl. Do this for
4-6 seconds then proceed to start the engine.
