85 Bronco,fuel gauge won't work

We just bought a 1985 bronco,did'nt know that the fuel gauge did not work.Where should I start?

Check the sending unit, I have a '85 bronco II and have the same problem and the sending unit is out.

I'd look at the send unit float. if it has a hole in it, it will fill with gas and cause it to read empty all the time. new floats are around $8 from Ford...but can be a PITA to get to without dropping the tank.

this seems to be a common problem in ford trucks of varying vintages. I know several people who have had this problem. Unfortunatly in most cases you have to drop the tank.
