I sort of had the same problem with my fuel gauge. Mine would only work when the tank was at least at halfway mark or more. As soon as the tank went below one half, down to empty the gauge would go. I finally pulled the old sending unit from the tank and replaced it with a new one. All is well now, and it works just fine. I know most guys don't really care for fuel gauges, but I like being able to see when I need to go for fuel, even if it isn't the most accurate. I guess it is for piece of mind. Cheap fix if you decide to go that route. The original sending unit was a simple float arm type and those can be bought anywhere cheap. Good luck with yours.
