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, 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
replacement filters are Motorcraft Part No. (FD-4604, F-Series) and
(FD-4606, E-Series).
FCM/HFCM drain procedure
1. Stop the vehicle and shut off the engine.
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).
