Wacky Fuel Guage Reading

Had my 1983 10 Meter out for the 3erd time this weekend and my fuel guage went from half full to empty. It stayed at empty even when I stopped the boat. Then it would jump to quarter and back up to half full and land back on empty. I tought I had half a tank but being a new to me boat I wasn't sure. I decided to fuel up and it only took 70 gallons to fill her. The guage now shows full. Does it sound like a bad ground or guage starting to go bad. Any ideas where to start?

Lose wire or most likely a bad sending unit the gauge it self should be OK .
