Hello, I've only had this yukon about 2 months. When I fill it up, it reads way past full like at the 3 o'clock position. I was told by previous owner that when it gets to 1/4 tank to find a gas station and that worked until I ran out of gas @ a little under 1/2 the other day. The hand bounces alot from 3 to 12 o'clock when full but after a couple of days it don't bounce at all. Any help would be greatly appreciated.
