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 pip
e.
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, service
interva
ls, 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 Fi
lters
A primary fuel filter is installed between the fuel
tank a
nd 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 location of a primary fuel filter is important in cold
weather operation. The primary fuel filter and the fuel
supp
ly line are the most common components that
are affected by cold fuel.
Fuel Heaters
Not
e: The OEM may equip the application with fuel
heaters. If this is the case, the temperature of the fuel
must not exceed 73 °C (163 °F) at the fuel transfer
pum
