  • Patent number: 5285744
    Abstract: An extended flexible polyurethane inner hose defines a fuel supply passage and is surrounded by an unbonded braided nylon reinforcement filament. The inner hose extends within a molded polyurethane and flexible corrugated outer hose which defines an annular fuel vapor return passage around the inner hose. Corresponding end portions of the hoses are connected to a fuel dispensing nozzle by a tubular metal inner coupling member, a tubular nylon outer coupling member, and a nylon nut. A small flexible fuel evacuation tube extends within the lower portion of the vapor return passage adjacent the inner hose, and an annular rotary coupling or union member and ring seals are confined between the inner and outer coupling members to define a fuel evacuation passage which connects the evacuation tube to a corresponding tube within the dispensing nozzle.
