Abstract
A vent valve assembly is provided which will allow a probe for a gauging system to be added to underground fuel tanks which include a vapor recovery system. The support assembly replaces existing float valve assemblies and combines a valving structure with a support for a fuel system gauge probe. A gauging system may be easily and inexpensively added to existing underground fuel tanks with minimum disruption to the operation of the gas station.
