Fuel Filter
Important information on replacing engine
mounted cartridge type fuel filters.
Perform these maintenance procedures
according to the Preventative Maintenance
Schedule.
WARNING
When removing the fuel filter, a quanti-
ty of fuel will escape. DO NOT smoke
or allow an open flame in close prox-
imity. Failure to do so could ignite a
fire or cause an explosion which could
result in serious injury to you and/or
bystanders. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
NOTE
The fuel filter and the hand pump are
located on the left-hand side of the en-
gine, as viewed from the driver's seat.
NOTE
Use of poor quality fuel may require
more frequent fuel filter element serv-
ice.
Description
The fuel filter/water separator module
provides fine-particle filtration, water
separation, water-in fuel-sensing,
automatic water draining, lifetime
purification of drained water with a
charcoal filter, 12V preheating and system
manual priming in a singular easy to
service module.
Replace the suction side and the pressure
side fuel filters at the same time. It is
recommended to replace the fuel filters at
the same interval as the oil and oil filter are
changed. If the oil drain interval being used
is greater than 15,000 mi (24,000 km), as
determined by the Engine Lubrication and
Filter Intervals, the fuel filter change can be
extended until the oil drain interval.
NOTE
The engine and fuel module should be
operated in cold climates with accepta-
ble cold climate fuel blends which no-
ticeably reduces wax gelling in the fuel
filter cartridge. The fuel module in-
cludes a 12V preheater to support pre-
heat of the fuel for initial start-up in
mild climates. Failure to operate with
acceptable cold climate fuel may result
in insufficient fuel flow to the fuel injec-
tion system.

as biodiesel, and additional information for
