3. After replacing the air cleaner, be sure that the rubber water drain
hose is not kinked under the tray. If so, adjust the hose so that it hangs
free. Failure to do so may result in severe engine damage when driving
through deep water and/or encountering unusually heavy precipitation
conditions.
FUEL FILTER/WATER SEPARATOR
The engine is equipped with a combination fuel filter/water separator
located in the ªVº of the engine.
Water should be drained from the
filter bowl whenever the warning
light comes on or every 8 000 km (5
000 miles). The WATER IN FUEL
light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the separator.
Replace the fuel filter with Motorcraft Part No. FD-4595±A (Ford Part
No. F4TZ-9N184±B).
Fuel filter/water separator drain procedure
1. Stop the vehicle andshut offthe engine.
The vehicle must be stopped with the engine off when draining
the filter bowl. Fuel may ignite if separator is drained while the
engine is running or vehicle is moving.
2. Open the hood. Place an
appropriate container under the
filter drain under the vehicle.

3.On F-Series models,open filter
drain valve by turning clockwise.
Allow to drain for approximately 25
seconds or until clean fuel is
observed. Close drain valve by
turning counterclockwise until firmly
seated.
3.On Econoline models,open filter drain valve release handle. Allow
to drain for approximately 25 seconds or until clean fuel is observed.
Close drain valve by resetting handle to original position.
4.On all models,verify that the fuel drain is closed. Close the hood and
remove the container from under the vehicle.
5. Restart the engine and check WATER IN FUEL indicator light. The
light should not glow. If it continues to glow, have fuel system checked
and repaired.

The complexity of the diesel engine makes it so the owner is discouraged
from attempting to perform maintenance other than the services
described in this supplement.
If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
²a plugged air inlet system.
²water in the fuel filter/water separator.
²a clogged fuel filter.
²contaminated fuel.
²air in the fuel system, due to loose connections.
²an open or pinched sensor hose.
²low engine oil level.
If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
FUELING
Do not use starting fluid such as ether or gasoline in the diesel
air intake system. Such fluids can cause immediate explosive
damage to the engine and possible personal injury.
If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5±10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don't depress the nozzle trigger fully).
Do not run your diesel vehicle out of fuel as this will allow air to enter
the fuel system which will make restarting difficult. Longer engine
cranking time may be required once air is in the fuel system. If air enters
the fuel system (either through running the fuel tank(s) empty or during
a fuel filter change), the engine will self-purge the trapped air once it
starts running. The engine may run roughly and produce white smoke
while air is in the fuel system; this is normal and should stop after a
short time.
