If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer toDraining the FCM/HFCM and changing the fuel filtersin the
Maintenance and Specificationssection of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
Do not drain the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
Engine air filter (if equipped)
The engine air filter warning light illuminates when the air filter
restriction gauge reaches the CHANGE FILTER mark.
Type A
Type B
Type C
The condition should be verified by inspecting the underhood air filter
restriction gauge; the warning light is only a secondary indicator. Always
use the underhood air filter restriction gauge to determine when the air
filter element needs to be changed.

The vehicle may be driven with the engine air filter warning light
illuminated/or when the underhood air filter restriction gauge has moved
to the CHANGE FILTER mark for up to 400 km (250 miles) without
damaging the engine or related components. However, the air filter
element must be replaced at the earliest opportunity. Refer toAir filter
restriction gauge (if equipped)in this section of the supplement for
more information.
Transmission Tow/Haul Feature
(if equipped):Illuminates when
the Tow/Haul feature has been
selected. Refer to theDriving
chapter for transmission function and operation. If the light flashes
steadily or does not illuminate, have the transmission serviced soon, or
damage may occur.
Air filter restriction gauge (if equipped)
The restriction gauge, located on
the upper housing of the air cleaner
assembly, monitors the condition of
the air filter element in two ways:
•First, the colored indictor inside
the gauge highlights the
percentage that the air filter
element is clogged with dust or
contaminants. Refer to
Maintenance and Specifications
section of this supplement.
•Second, the gauge contains an
electrical switch which illuminates
a warning light on the instrument
cluster when the air filter element
is 100% clogged. Refer to the
Engine air filterwarning light in
this section of the supplement.
Check the air filter restriction gauge
whenever the hood is raised to
perform general engine maintenance at least every 7,500 miles (12,000
km). If the vehicle is operated in extremely dusty conditions, check the
gauge at least every 500 miles (800 km), or two weeks, whichever comes
first.

The air filter element must be
replaced when the colored band on
the gauge reaches the CHANGE
FILTER mark. Engine performance
and fuel economy are adversely
affected when the maximum
restriction is reached.
Blowing-out the air filter
element with compressed air is
not recommended as the
compressed air may damage the
filter paper.
Note:It is not possible to determine
the level of filter clogging by visual
appearance alone. A filter which
appears to be dirty may actually
have several thousand miles
(kilometers) of life remaining.
Always use the underhood air
filter restriction gauge to
determine when the air filter element needs to be changed. The
warning light on the instrument cluster should not be used
exclusively for determining when the air filter element needs
changing.

After servicing the air filter element,
reset the restriction gauge by
pressing the button on the end of
the gauge.
Note:If the vehicle is operated in a
heavy snow storm, in blowing snow
or the vehicle is equipped with a
snowplow, the engine air filter
element may become partially
clogged with snow and/or ice. If this
occurs, the air filter restriction
gauge will move to the CHANGE FILTER mark and the engine may
experience a significant reduction in power output. The vehicle may be
driven under these conditions for up to 160 km (100 miles) without
damage to the engine or related components.
At the earliest opportunity, clear all snow and ice from the air induction
system and reset the restriction gauge by pressing the button on the end
of the gauge. If the air filter restriction gauge moves the CHANGE
FILTER mark after clearing snow and/or ice, then replace the filter.
Reset filter restriction gauge after changing the air filter element.
The air filter warning light on the instrument cluster may be used, in
addition to the underhood restriction gauge, to monitor the condition of
the air filter element. Refer to theEngine air filterwarning light in this
section of the supplement.
Engine boost gauge (if equipped)
Indicates the amount of pressure in
the engine. Driving with your

FUEL CONDITIONER MODULE (FCM - E-SERIES)/HORIZONTAL
FUEL CONDITIONING MODULE (HFCM - F-SUPER
DUTY/EXCURSION) - FUEL FILTER/WATER SEPARATOR
HFCM - F-Super Duty/Excursion
The vehicle is equipped with a Horizontal Fuel Conditioning Module
(HFCM) located on the frame-rail under the driver-side floorboard near
the transmission.
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the module.
Replace the fuel filters with Ford Part No. FD–4604. This part number
includes filters and seals for both the engine-mounted and
frame-mounted filters.
FCM - E-Series
The vehicle is equipped with a Fuel Conditioning Module (FCM) located
on the driver-side of the vehicle next to the transmission case.
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the module.
Replace the fuel filters with Ford Part No. FD–4604. This part number
includes filters and seals for both the engine-mounted filter and the FCM
filter.
DRAINING THE FCM/HFCM AND CHANGING THE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine.On F-Super Duty and Excursion vehicles,the second
filter, inside the HFCM, is mounted inside the frame rail under the
driver-side floorboard near the transmission.On E-Series vehicles,the
second filter, inside the FCM, is mounted on the driver-side of the
vehicle next to the transmission case.On all vehicles,both filters
should be replaced at the same time. The Motorcraft part number for the
replacement filters is FD-4604.
