2004 GMC Yukon V8 Four Wheel Drive Automatic 62k miles
Recently my fuel gage has gone out of calibration. When full, it reads past the full mark. When empty it reads 1/2 a tank. Do I need to pull the dash and turn the dial or is there another way to calibrate it?

The first thing I would check is the sending unit. Is this a single tank vehicle, how many gallons does the tank hold? The voltage and ohms specs are different for different tank sizes.
