11-32 Pretrip inspection and maintenance
If the water in fuel warning illuminates, there is
too much water in the fuel filter.
Drain the fuel filter as follows:
1. Provide a container to collect the water.
2. Disconnect the electrical connector on the sen-
sor .
3. Turn the sensor clockwise (in the direction of
arrow ) to loosen it. The water will flow from
the tube at the end of the sensor.
To make the water drain faster, operate the
priming pump (press the pump handle about
7 times).
4. When fuel begins to flow, close the drain port by
tightening the drain plug counterclockwise (in
the direction of arrow ).
5. Attach the electrical connector and tighten the
sensor.
6. Bleed the fuel system. P. 12-23
7. Start the engine and check for fuel leaks. Check
the fuel tank, cap and lines for leakage. Correct
any leaks found.
Fuel filter draining
WARNING
• Diesel fuel is combustible and can ignite if
exposed to open flame, intense heat, or
other source of ignition. A fire could result
in burn injuries or loss of life.
• Be careful when gaining access to the fuel
filter. Clearances are tight in this area.
Contact with sharp or rough surfaces
could cause personal injury.
Sensor torque 60-80 lbf·in (400-600 N·cm)
WARNING
• The drained fluid contains a mixture of
water and fuel. Be sure to wipe clean all
surfaces around the fuel filter.
• Make sure fuel does not leak from the filter
or from other parts of the fuel system.
Any spilled or leaked fuel could cause a fire
that could result in burn injuries and loss of
life.
