I know it's not as easy as they make it sound because most need a special fuel line disconnect tool to remove the lines from the filter ends.


Hope this helps.

Things You'll Need

• Drop pan
• Socket set
• Fuel line disconnect tool
• New filter

• 1Slide the drip pan under the driver side of the truck, below the driver door. Climb under with the socket set, fuel line disconnect tool and new filter.
  
• 2Unbolt the fuel filter retaining strap with the socket set. The filter is located along the inboard side of the frame, below the driver seat. When in doubt, simply follow the fuel lines forward from the fuel tank until you locate the filter.
  
• 3Disconnect the front fuel line from the fuel filter with the fuel line disconnect tool. The line flares out where the filter outlet enters it and a retaining clip holds it in place. You can unseat this clip with a pocket screwdriver or a pick, but it's not advisable, as the clip tends to break if pried on unevenly. hence why u need the tool. about ten buck
  
• 4Pull the fuel line off the front of the fuel filter and then pull the filter out of the rear line and retaining strap. Put the old filter in the drip pan.
  
• 5Slide the new filter into the retaining strap and plug the inlet into the rear fuel line. Make sure the arrow indicating flow direction points toward the engine. Connect the front fuel line, push the retaining clip back into place and bolt the retaining strap back to the frame.
  
• 6Climb out, get in the truck and turn the ignition key to the run position. Wait for the fuel pump to stop running (this should be about 10 seconds) and start the truck.
  

you need a fuel line disconnect tool

go to auto parts store..ford has a special tool to remove the line

Yes you do, The first clips you removed are the secondary clips. The lines have to be released from the inside. Heres the info.. Cobra :-)
Removal

1. Open safety clip.
   
   
   
   

1. Fit Tool T90T-9550-B (5/16 inch) or T90T-9550-C (3/8 inch) to coupling so that tool can enter female fitting.
   
   
   
   

1. Push the tool into female fitting to release the retaining fingers from the formed male tube end.

1. Pull male and female fittings apart.
   
   
   
   

1. Remove the tool from the disconnected fitting.

1. Inspect the fitting for any internal parts that may have been damaged. Fuel tube should be replaced if internal parts are damaged.

1. Before servicing the vehicle, refer to the Precautions Section.
   
2. Disconnect the negative battery cable and relieve the fuel system pressure.

1. Disconnect the fuel lines from the fuel filter. Have a drain pan handy to catch any residual fuel once the lines are separated. On newer models, disconnect the fuel lines from the filter as follows:

1. Disconnect the safety clip from the male hose.
2. Install and push the fuel line disconnect tool into the female fitting.
3. Separate the male and female fittings.
4. Inspect the fuel lines for any damage after the fuel is finished draining.

1. Remove the fuel filter from the bracket and the retainer, if equipped. Note the direction of the flow arrow so the replacement filter can be installed correctly.

To install:

1. Position the fuel filter into the mounting bracket with the flow arrow pointing in the correct direction.
2. Install the fuel lines to the fuel filter. On newer models, align and push the male tube into the female fitting until a click is heard. Pull on the fitting to ensure that it is fully engaged, then install the safety clip.
3. Lower the vehicle to the ground.
   
4. Re-install neg. batt. cable to battery.
   

the fuel filter is located on the drivers side frame rail near the tranny crossmember your gonna need a fuel line disconnect tool which you can pick up at your local advance auto,you insert the tool in each side of the fuel line and push the tool towards the line while holding the fuel line against the tool and pull the fuel line off while your twisting it slighty it may take sum force but it will slide off,once you get the lines off pull out on the body of the filter it will pop out of the bracket,oh before you start remove the metal safety clips on the lines and reinstall them when your done

Inside the frame rail on the driver's side. You'll need a 5/16" (8mm) socket if it is the type that is held in with a hose clamp, or a 10mm if it is the bracket type. Some of the lines are held in with white plastic clips, others by special springs. If it is the type without clips, you'll need a special tool to release them. Also, if it is the type without the plastic clips, make sure they gave you the right filter. If the new filter is shorter than the old DO NOT PUT IT ON. If you do, you will have to cut it off next time you have to change it as the tool will not fit in. The two filters look the same except the tubes are longer on the non-clip filter.

The clamps are just a secondary lock, special tools are needed to unlock the fuel lines.

unbolt the filter from the bracket, that is a 5/16" machine screw head size, then remove the nylon clips that hold the lines onto the filter, hold a rag over the fuel line when u remove it, it will have about 30 pounds of pressure.
