ABSTRACT:
Dual concentric fuel and vapor recovery hoses are disclosed wherein an inner substantially kink-proof reinforced pressure hose carries fuel while an outer larger diameter extruded cover hose provides a vapor recovery path between the two hoses. The dual concentric hoses terminate into an end fitting that provides for separate rotatability of the hoses while also providing direct fuel feed through the fitting and a parallel vapor recovery path.
