Abstract (en)
In a coaxial hose system for a fuel distribution system, a product delivery hose (120) is centrally located within a vapor recovery hose (82), whereby the area between the product and vapor hoses provides a return path for vapors developed at a nozzle during refueling of a vehicle. A venturi pump (64) is located in the product hose (120) line, and operable over a range of flow rate of the fuel through the product hose (120), for sucking fuel back into the product hose (120) from an area of the vapor path where fuel may accumulate due to backflow from the nozzle (128), thereby substantially insuring a clear vapor path and more complete delivery of metered fuel.
