Fuel Filter
The fuel filter is located approximately mid-way
between the engine oil filter and the air cleaner.
1. Before servicing the fuel filter, perform the
“Man-
datory Safety Shutdown Procedure
” on page 2-2.
1. Twist the fuel shut-off valve lever (2, Figure 4-8)
on the water separator to the “OFF” position, as
shown.
2. Clean dirt from the housing and unscrew the fuel
filter (1, Figure 4-7).
3. Remove and discard the old fuel filter properly.
4. Clean around the filter housing.
5. Coat the seal on the new fuel filter with clean
engine oil.
6. Install the new fuel filter and tighten 1/2 rotation
past where the filter contacts the filter mounting
surface.
7. Twist the fuel shut-off valve (2, Figure 4-8) on the
water separator to the “ON” position.
The fuel system must be purged of air after changing
the fuel filter, or if the fuel tank has been run dry. See
“Purging Air from the Fuel System
” on page 4-14.

Fuel Shut-off Valve and Water Separator
If water is seen in the water separator bowl or the indi-
cator ring rises to position (4, Figure 4-8), the bowl will
need to be drained.
Note: The water separator is located on the engine
below the air cleaner.
1. Twist the fuel shut-off valve lever (2) on the water
separator to the “II” (OFF) position, as shown.

and Water Separator (Shut-off valve in “OFF
position)
2. Unscrew plug (3) and collect the water that drains
out of the water separator. Allow water to drain
until the indicator ring reaches the bottom of the
water separator.
3. Tighten plug (3) and discard fuel/water according
to environmental laws. DO NOT pour fluids onto
the ground or down a drain.
4. Twist the fuel shut-off valve (2) on the water sepa-
rator to the “I” (ON) position.
Purging Air from the Fuel System
Starting from the fuel tank, the fuel system runs
through the water separator, fuel filter, fuel injection
pump and high pressure piping to the fuel injection
nozzles. If the fuel tank is run dry, or if the fuel filter,
water separator or fuel lines are replaced, trapped air
must be removed, or bled, from the fuel system.
WARNING
Use care to catch any spilled fuel when ser-
vicing the fuel filter. Spilled fuel can cause a
fire.
