ABSTRACT:
A fuel dispensing system and method for making same having a fuel dispensing hose connecting between a dispenser pump and nozzle that has a flexible inner tube defining a fluid conduit, and a tubular outer sleeve that defines with the inner tube an annular vapor return passage. The system includes a venturi section adapted for serial connection with the inner tube within the outer sleeve. The venturi section comprises a cylindrical block that connects at each end with an end of the inner tube and defines a venturi opening part of the fuel conduit. The vapor return passage forming at least one looped low portion during dispensing of fuel. The block also has an aspirator mechanism that defines a plurality of separate radial ports communicating between the venturi throat and the annular vapor passage. The ports are formed so that one of the ports will be below the centerline of the looped portion during dispensing of fuel. Liquid fuel that condenses or collects in the annular vapor return passage and is sucked through the aspirator mechanism due to suction produced by the venturi throat.
