Fuel and Refueling • 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. 32 2013 Diesel (67l) Supplement, 1st Printing USA (fus)
