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. The opposite end portions of the inner and outer hoses are connected by corresponding tubular coupling members to a fuel dispensing pump, and a support yoke, clamping ring and nut cooperate to prevent rotation of the hoses after they are connected to the dispensing pump. The nylon outer coupling members and nuts are carbon filled to be electrically conductive and are connected by a static wire helically wound around the inner hose.
