I have a question. We are all susposed to have a 21.1 gallon fuel tank correct? Or something close to that number of gallons. Anyways, it seems like everytime i drive and get low enough to have the low gas light come on, i go and fill it up and its never taken more than 16 or 17 gallons to fill the tank to the brim. The dealership told me that the light comes on with there still being 3 to 5 gallons of gas in the tank because the fuel is what is cooling the fuel pump. So..........anyone else have any thoughts on this one? Do i have something wrong with the sensors in my truck? Are the guys at my dealership retarded?
