ABSTRACT:
A fuel hose assembly having an inner and outer hose that have their respective ends secured to a coupling member that retains their ends in spaced apart positions thereby defining separate passageway while permitting the hoses to rotate relative to each other. The coupling member has means for rotating the fuel hose assembly relative to their connection to a fuel dispensing pump and vapor recovery system such that the one hose will convey the liquid fuel while the other hose will convey the fuel vapors that are displaced from the tank being filled with the liquid fuel. Sensing means are provided to prevent the flow of the liquid fuel via the vapor recovery passageways.
