ABSTRACT OF THE DISCLOSURE A liquid jet gas pump providing suction to recover vapor through a line connected to dispensing nozzle, the pump having chambers for collecting liquid carried by returning vapor and a float therein so that the float, when the amount of liquid collected in the chambers becomes too great, blocks the suction path through the pump thereby shutting off the dispensing nozzle. The pump also has an internal connection from a diaphragm chamber to an internal area which is substantially at atmospheric pressure during pump operation thereby eliminating the need for an access vent from the diaphragm chamber to the atmosphere.
