ABSTRACT:
A barrier vapor control system includes a seal inside an automobile filler pipe for engaging the fuel delivery conduit of a pump nozzle to prevent the escape of hydrocarbon vapors out of the filler pipe into the atmosphere while the fuel tank is being refilled. A vapor recovery conduit downstream of the seal carries the vapors displaced by filling the fuel tank to a cannister that contains a scrubbing agent. A vacuum accumulator and a vacuum pump draw fresh air and the vapors from the fuel tank through the cannister to remove hydrocarbon vapors from the effluent vapors of the fuel tank.
