i think i may have had exactly the same problem, when i got my '95 accord the gas guage wouldn't fill all the way up, sometimes it would go all the way down and come back up while i was driving, or it would go down fast and read empty when i still had 1/2 tank left. i had to get the sending unit replaced (i couldn't take it anymore) and it was about $175 at the honda dealership. i guess it is the part in the gas tank that tells the guage how full the tank is that goes bad or something, i really don't know but that was my problem. hope that helps.
