Lately, my fuel gauge is going all over the place. I put some gas in it, and it shoots up to almost full. When I start the car, it will go up over half, then come back down and read correctly. Any idea what causes that?

I had this same problem before I replaced mine. It turned out that my original fuel level sensor was completely stripped and couldn't read correctly anymore at all. I ran out of gas a couple of times on the street because I had to resort to guessing after a while

What did this turn out to be? I have the hatch already cut in the back so its easy to get to but I want to know what to get at first. Is the sensor on the top cap where the wires connect or inside the tank on the bar/float? My fuel gauge is fluctuatig pretty bad now and the service engine light comes on when it goes down to empty.
