GATOR IS RIGHT!!!!! I broke a retaining ring (located inside the fuel line fittings) because I didn't know what I was doing. Ford wanted $450 to fix it. Nobody makes the retaining rings that install inside of the fuel line. I had to cut off the fuel line that had the broken ring and splice on a fuel line with a different style fitting that I got at Napa.
Technically, you're supposed to use a fuel line disconnect tool to remove the fuel lines, but you can remove the lines from the filter by pushing the colored ring (visible through a slot in the fitting on the hose end) with your thumb, while simultaniously pulling the fuel line off of the filter.
Be sure to de-pressurize the fuel system first; you will get some good spray. And have a pan under the truck, as you will lose a lot of fuel from the lines and the filter. If you rotate the filter 90 degrees, what fuel is left in it will pour out (about a pint!).
Here's some good info with a lot of good advice from the R-F members:
