gas gauge problems

[janea]

I have a 1995 Jetta 3.Sometime last year the gas gauge started to act up.If I fill the tank the gauge works normally until I hit a half tank and then the gauge goes sort of haywire.It drops down to empty and then slowly climbs up a notch or two and then back to 1/2 tank and does this repeatedly until I fill-up again.Does anyone have an idea what the problem could be?

Most likely the sending unit in the tank.

It's inside the fuel tank. There is an access cover in the front left of the luggage compartment area.
