Cliff's link works well if you have the Ford IDS scanner to check the PIDs. Sounds to me like you have a bad fuel sender most likely. The fuel gauge works off ohm readings. As it sweeps the resistance will vary and cause the gauge to move. I'd drop the tank and pull the assembly out, and check the resistance as you manually move the float up and down

It could be a shorted wire 'tween the sender and the instrument cluster--have you changed anything, had any damage, etc?
Use the HEC (Hybrid Electronic Cluster) self-diagnosis mode to examine the FUEL parameter (bottom of page 1).
If the observed value is between 93 and 215 then the problem is in the fuel gauge itself¹, not the wiring, if it is less than 40, or 0-18, then there is a wiring short.
----------------------------------------------
¹ - The "gauges" are servo-motors driven by the instrument cluster micro-controller, if the HEC diagnostic digital value is between 41 and 230 then the gauge motor is bad.

cliffy - i had the steering column down for a couple days, but after reinstalled, the gauge was working. as far as i remember, it was working, i parked it for a few days (week maybe) and got in it one day and it was on E... there was a good amount of time between the steering column being down and the issue too....
kugz, thanks man. not the worst issue in the world. im using the trip meter when i do drive the car right now, and just being cautious. but would be nice to know how much gas i have, haha.
