Fuel Shut-off Valve and Water Separator
If water is seen in the plastic water separator bowl or
the indicator ring rises to position (3), the water will
need to be drained. See Figure 4-7.
Note: The water separator is located behind the engine
underneath the engine cover.
1. Twist the fuel shut-off valve lever (2, Figure 4-7)
on the water separator clockwise to the “OFF”
position.

2. Unscrew plug (4) and collect the water that drains
out of the water separator. Allow water to drain
until the indicator ring returns to the bottom of the
water separator.
3. Tighten plug (4) and discard fuel/water according
to local regulations. 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 (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.
Bleed air from the fuel system according to the follow-
ing steps:
1. Fill the fuel tank.
2. Make sure that the valve on the water separator (2,
Figure 4-7) is in the “open” (ON) position.
3. Turn the ignition key to the “I” (ON) position.
4. Wait about five minutes while the fuel system
automatically bleeds itself.
5. Start the engine.
If the engine runs smoothly and then stops, or if it does
not run smoothly, switch off the engine and bleed the
system again as described in this procedure. If the
engine still does not run smoothly, contact your dealer.
