摘要： A gasoline flow control device for regulating the flow of gasoline through a gasoline pump handle comprising a body having an upper and a lower spaced-apart surface thereon, the upper surface having a plurality of steps therein varying in distance from the lower surface on the body. Each step on the upper surface is concave in configuration and the lower surface includes a plurality of ridges and valleys cut therein forming an irregular surface thereon. The method of using the control device includes the steps of first moving the trigger on a gasoline pump handle a sufficient amount to begin the flow of gasoline therethrough and then wedging the body between the moved trigger and trigger guard on the handle with the lower surface gripping the trigger guard and the trigger itself resting against one of the steps on the upper surface thereof. To guarantee the suitability of the control device for use on the great majority of gasoline pump handles presently in existence, the distance from the lower surface to the most distant step on the upper surface should be about three inches with the other steps being sequentially closer to the lower surface in order to provide for differing rates of gasoline flow.
