Abstract
Abstract A blending-type liquid fuel dispensing apparatus is provided with two separate nozzles, one a special nozzle for dispensing only low-lead or lead-free (unleaded) fuel, and the other a more conventional nozzle for dispensing blends of this fuel and a highly leaded fuel, as well as the highly leaded fuel alone. The apparatus has an interlocking arrangement which permits either nozzle to be utilized separately, but which prevents utilization of both nozzles simultaneously.
