Fuel Tanks
Condensation can form in partially
fi
lled fuel tanks.
Top off the fuel tanks after you operate the engine.
Fuel tanks should contain some provision for draining
water and sediment from the bottom of the tanks.
Some fuel tanks use supply pipes that allow water
and sediment to settle below the end of the fuel
supply pipe.
Some fuel tanks use supply lines that take fuel
directly from the bottom of the tank. If the engine is
equipped with this system, regular maintenance of
the fuel system
fi
lter is important.
Drain the water and sediment from any fuel storage
tank at the following intervals: weekly, oil changes,
and refueling of the fuel tank. This draining will help
prevent water and/or sediment from being pumped
from the fuel storage tank and into the engine fuel
tank.
Fuel Filter
A strainer and fuel
fi
lter is installed between the
fuel tank and the electronic fuel injectors. After you
change the fuel
fi
lter, always prime the fuel system
in order to remove air bubbles from the fuel system.
Refer to the Operation and Maintenance Manual in
the Maintenance Section for more information on
priming the fuel system.
