ABSTRACT:
A fuel tank filler including a positive vapor return vent system that prevents substantial loss of vapor or liquid is provided using an arrangement of relatively light weight and low cost coupling members. A guide provided together with the arrangement of the couplings requires connection of the vent coupling before the fill pipe is connected and until it is disconnected so that fuel cannot be added unless the return vent is operative.
