ABSTRACT:
A combined filler neck and vapor vent line valve is provided by inner and outer pipes that are maintained in concentric relation by a sleeve tightly inserted between the outer pipe and an out-turned flange at the end of the inner pipe. This provides a convenient path out of the fuel tank for displaced tank vapors. Vapor control is provided by a stepped cylindrical valve body that rides up and down within the upper end of the inner pipe and the sleeve so that a seal on the outside of the valve body can cover and uncover openings in the flange to block and un-block a vapor path to the canister.
