We took a 600 mile trip this past weekend, filled up with fuel about 100 miles out, and suddenly the fuel gauge started bouncing all over the dial. When we stopped for breaks, it seemed to be showing the correct fuel level based on my best guess. On the way home, the gauge still bounced all over, and sometimes for miles it would just stay at the far right (way past full) on the dial.
I'm guessing a sensor of some sort in the fuel tank is the culprit. Or perhaps a faulty gauge.
Any ideas would be appreciated.
