Normal operation: If the message appears during normal operation
when the vehicle / engine is fully warm, and fuel level is not low, the
fuel filters must be changed regardless of the maintenance schedule
interval.
•
If replacement of the fuel filter does not remedy the low fuel pressure
message during normal operation as defined above, take the vehicle to
your authorized dealer.
CHANGING THE ENGINE-MOUNTED AND DFCM FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the driver’s side of the engine and the second filter, inside the DFCM, is
mounted on the frame rail under the driver-side floorboard near the
transmission. 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 information
of this supplement for more information.
Refer to
Motorcraft part numbers
in the
Maintenance
chapter for the
fuel filter replacement part number. This part number includes filters
and seals for both the engine-mounted and frame-mounted filters.
Removal - DFCM filter
The DFCM filter is located in the lower portion of the DFCM housing.
1. Drain the DFCM. See
Fuel filter/water separator
in the
Fuel and
Refueling
chapter.
To install the new DFCM filter, see
Installation – DFCM filter
in the
Fuel and Refueling
chapter.
2. Remove the lower portion of the
DFCM housing (filter bowl) by
turning it counterclockwise using a
32 mm socket.
Note:
Depending on the amount
seal swelling, removal of the filter
bowl may be noisy and require some
effort. Replace the seal prior to
reinstalling the filter/bowl to
improve assembly.
3. Remove and discard the old fuel filter element.
4. Carefully clean the mating surfaces using a lint-free rag.
