ABSTRACT:
In order to prevent malfunctioning of an automatic liquid fuel dispensing nozzle which is being used for vapor recovery while dispensing, the pressure inside the tank (into which liquid fuel is being dispensed) is used as a reference pressure for the actuating diaphragm of the nozzle cut-off arrangement, rather than using atmospheric pressure for this purpose. Displaced vapors from the tank are directed through a vapor recovery boot having a flexible, exterior cylindrical sleeve and an interior of reticulated material which provides passageways for the vapors to travel through.
