Abstract
A fuel tank assembly is fillable by a fuel pump. The fuel pump is configured such that the existence of a predetermined condition causes the pump to stop delivering fuel. The fuel tank assembly includes a tank defining a chamber, a fill tube, and a fuel pump shut-off system. The fill tube defines an opening configured to receive a nozzle of the pump, and a passageway that provides fluid communication between the opening and the chamber to transfer liquid fuel from the nozzle to the chamber. The fuel pump shut-off system is configured to selectively generate the predetermined condition, and is configured such that whether the predetermined condition exists depends on the total volume of liquid fuel in the chamber and the chemical composition of the liquid fuel in the chamber.
