Fuel Tanks

Condensation can form in partially filled 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 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 will help prevent
water and/or sediment from being pumped from the
fuel storage tank and into the engine fuel tank.

Fuel Filters

It is possible that a primary fuel filter is installed
between the fuel tank and the engine fuel inlet. 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.
The micron rating and the location of a primary fuel
filter is important in cold weather operation. The
primary fuel filter and the fuel supply line are the most
common components that are affected by cold fuel.

Fuel Heaters

Note: The OEM may equip the application with fuel
heaters. If this is the case, disconnect an electric type
of fuel heater in warm weather in order to prevent
overheating of the fuel. If the type of fuel heater is a
heat exchanger, the OEM should have included a
bypass for warm weather. Ensure that the bypass is
operational during warm weather in order to prevent
overheating of the fuel.
For more information about fuel heaters (if equipped),
refer to the OEM information.
