Gas Gauge Malfunction on 1998 Buick Park Avenue

The gas gauge needle has gone past full, all the way around and now sets below the pin the indicates "empty". This happened when I changed the battery. How do I get the needle back around to the proper area so it reads the gas level?

Get a strong magnet maybe from Harbor Freight or any good hardware store. Use it to drag the needle back into place. A shop repair for this will cost you $100. A cheap magnet may cost a buck.

Use a magnet and put it as close to the needle as you can. Then start slowly moving it to the right pulling the needle to the correct position then start the car and it will lock in the proper position.
