Fuel Related Components in Cold Weather
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 filter 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 procedure will help
prevent water and/or sediment from being pumped
from the fuel storage tank and into the engine fuel
tank.
Fuel Filters
The engine must have an in-line fuel filter installed
between the fuel tank and the electric operated fuel
lift pump. After you change the fuel filter, 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.
Fuel Heaters
Fuel heaters help to prevent fuel filters from plugging
in cold weather due to waxing.
For further information on fuel heaters, consult your
Perkins dealer or distributor.
