Filled up my crossfire for the first time. Low gas light went on so I filled the tank until the nozzle shut off, only 3.8 gallons went in. I could tell the tank was actually full, gas was overflowing. When full, the gas gauge is at half full. So it moves, is just inaccurate/offset. I searched the forums but wanted to see what everyone thought. I reseated the two electrical connections under the center carpet in the trunk, did not help. How do you fully remove the center carpet?
