sandman, I had the same issue on my Kubota. The float arm got stuck in the "full" position. I have a "bad" habit of over filling the fuel tank and the float arm must have gotten stuck near the top. I was able to use a piece of coat hanger to push the float arm back down. That was years ago and never happened again.

Others have mentioned that there could possibly be a "ground" issue with the fuel gauge. Good luck with your problem. Stanley
