Sounds like the sending unit in the gas tank is going bad, like Archion said its very common on these older trucks.
You'll need to drop the gas tank if you wish to replace it, its not to hard to do.

Yeah,mine has just about the same problem.I'm pretty sure it's the sending unit.It's sitting at a little over half right now and it's empty as can be I'm pretty sure.The sending unit is right in the tank right?Sorry if it sounds like a dumb question.I sort of just came back from the chevys.So I've seem to of lost some of my knowledge on Fords,but it's coming back slowly but surely.Thanks a lot.

Yikes! You said the "C" word!
Seriously, the sending unit drops in from the top just like nearly every other. Loosen the filler hose, remove the straps, lower the tank and replace the sender.
No biggie (as long as your tank isn't too rusted where the retaining ring goes).
Now is a good time to check your filler neck too. They are notorious for rusting through also.

With it working somewhat, it is possible to be the float has some fuel leaked into it. The float is brass, and tend to pinhole, and when the float gets partially filled with fuel, it gets heavier, and throws the reading off.

The float would be sunken all the time, just like in a carb. The sender on these trucks is pretty much a potentiometer, when the contact fingers or carbon tracks wear down, it will give strange or erratic readings.
