Refer to Motorcraft part numbers in the Capacities and Specifications chapter for the fuel filter kit part number. See Motorcraft Parts (page 55). 2. Lube O-ring with lubricant packet in the filter kit. This will assist in making sure the filter is properly tightened. Removal - Engine-mounted fuel filter The engine-mounted fuel filter is a plastic disposable cartridge. To remove it, do the following: E163363 1. Disconnect both fuel lines by squeezing the connector tabs and pulling the lines straight off. E163362 3. Reinstall the lower portion of the housing by slowly turning it clockwise onto diesel fuel conditioner module housing, allowing fuel to soak into the fuel filter element. Tighten the lower housing until it contacts the mechanical stop. Note: The engine will not run properly if you do not install the diesel fuel conditioner module fuel filter in the housing or if the filter bowl is not tightened to the mechanical stop. Note: You will need to purge the system of air after removal or changing of the filter. See purging air from the fuel system later in this chapter. E163364 Note: Although the fuel system is not fully pressurized when the vehicle is off, some residual pressure may remain in the fuel system since it can take some time for the pressure to completely bleed off. Therefore, we recommend you place a shop rag below the filter connectors to absorb the small amount of fuel that will drain. 2. Rotate the filter fully counterclockwise until the peg is at the far end of the slot. 3. Pull the filter straight up from the bracket and discard the filter. 20 Super Duty (TFA) , enUSA
