Horizontal Fuel Conditioner Module (HFCM - F-Super Duty)
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 0.2 pints (100 cc) of
water accumulates in the module.
DRAINING THE HFCM AND CHANGING THE ENGINE AND
VEHICLE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine.
On F-Super Duty,
the second filter, inside the HFCM, is
mounted inside the frame rail under the driver-side floorboard near the
transmission.
On E-Series,
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. Regular fuel
filter changes are an important part of engine maintenance; failing to
keep with the scheduled maintenance could lead to engine performance
issues and/or fuel injection system damage. Refer to the
Scheduled
Maintenance Guide
chapter of this supplement for more information.
Refer to
Motorcraft Part Numbers
later in this chapter for the fuel filter
replacement part number. This part number includes filters and seals for
both the engine-mounted and frame-mounted filters.
1. Stop the vehicle and
shut off
the engine.
WARNING:
The vehicle must be stopped with the engine off
when draining the HFCM/FCM. Fuel may ignite if the separator
is drained while the engine is running or vehicle is moving.
2. Locate the HFCM and place an appropriate container under the drain
port (see illustration).
