2. Drain filter housing [yellow lever on base of housing] - close when done.
3. Unscrew the filter cap.
4. Remove old filter.
5. Remove old o-ring off cap thread base.
6. Visually inspect filter housing and see if there is any debris in the bottom. if there is you can clean it out, but make sure no dirt gets into the filter stand pipe [clean side].
7. Stick new filter in housing. It snaps into place in the cap. [added by RB]
8. Lube new o-ring with a little fuel oil or engine oil. [edited by RB]
9. Install cap back on housing [snug is good, too tight and you can split the cap]
10. Bump engine with starter to prime system for ±30sec or so.
11. Start engine, and visually inspect for leaks around filter housing.

Here it is reformatted and slightly edited... Nick, I hope you don't mind (or take offense):
I like JDiepstra's suggestion of doing step 10 twice.
However, on engines starting in 2004. 5 (and any pre-2004. 5 engines that have had the ECM flashed), the ECM programming was changed so that the fuel pump will run for 30 seconds after the key is turned to RUN, with no need to bump the starter! On those engines, it's not necessary to bump the starter.
Technically, the filter torque spec is 25 ft-lb, but I think that's probably a bit much. I normally just "snug" it, as Nick suggests.
