Fuel Filters
Fuel filters are located inside the mechanical
space. There is one water-separator type fil -
ter for each engine fuel line. Check all filters
for water frequently to ensure an adequate
supply of clean, dry fuel to the engines. The
filter elements should be changed once a
season.
Gasoline fuel filters
Turn off all electrical switches before servic -
ing the fuel system and DO NOT drain any
fuel into the bilge. Check all fuel lines and
fittings for leaks before and after starting the
engines and after any fuel system service.
Prime the fuel system and check all fittings
for leaks before starting the engines.

generator owner’s manual for information on
priming.
Make sure the fuel valve on top of the fuel
tank is in the ON position before attempting
to start the generator.
A water-separator type fuel filter is installed
near the generator. The fuel filter has a sed -
iment bowl that must be inspected for water
frequently to ensure an adequate supply
