Abstract
An adapter in the form of a sleeve which is permanently mounted inside the gasoline tank fillpipe of an automobile provides reaction points which maintain the spout of a gasoline dispensing nozzle with its axis approximately collinear with the fillpipe axis, when the spout is inserted into the gasoline tank for dispensing. The adapter insert (sleeve) has therein a sealing member which covers the air duct of the conventional automatic dispensing nozzle, thus preventing operation of the nozzle when the nozzle spout is inserted to less than a certain extent into the sleeve.
