Fuel gauge going crazy on the rear tank!
A few days ago I was running off of my rear tank and I looked down and my fuel gauge was going up. Then it went back down to where it should have been (half tank mark) then went below it to about a quarter, then all the way back up to full again. If I watched it close it contantly twitched and would randomly jump around all over the place. I filled up since I wasnt sure what was going on and it stopped jumping around until I got down to a half a tank then it started all over again. I filled up a third time and again it stopped. I havent got to a half a tank yet but i suspect it will start doing it again. any ideas what is going on. Thanks
