It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.Google+

fuel guage not reading correctly; does not even stay within the scale of the dashboard guage, but spins around through 360 degrees! Amusing to watch, but a pain in the a-- to drive with.

Hasn't worked right for 30,000 Miles. Can't trust it below 1/4 tank.
I never trust the gas gauge
