My Proton's gauge doesn't dance... BUT the Ironman! That fuel gauge could salsa, merengue, cha-cha, flamenco, tango, foxtrot, jitter bug, you name it!!! It was a dancing machine! I got used to it though. I never tried to fix it. If I was on a flat road, no problem. If I was going over some crazy bumps, and hills and stuff, I couldn't tell if I was empty or full. The "I am out of gas in a few minutes" light would come on when I needed gas so I figured I was ok.
