ABSTRACT:
Disclosed are various improvements in the vapor handling arrangements of a conventional fuel dispensing nozzle. In particular, there is shown a vapor shut-off valve that can override a vapor pressure regulator valve to seal the vapor conduit when fuel is not being dispensed; a magnetic sealing arrangement for preventing escape of vapor at the mouth of the vehicle fuel tank; and a relief valving arrangement to protect both the nozzle and the vehicle tank against excessive pressure conditions.
