Anti puddle valve

I was at a small show Sun. and a fellow showed up with a 36 Jr. 120 coupe. while looking at his car I noticed a tube running from the base of his intake manifold and it had a small device on the end. When I questioned him about it he said that it was an anti puddle valve. Supposedly it's purpose was to drain any gas that percolated from the carb when the engine was shut off while hot. I gather it was some sort of check valve otherwise it would be a vac. leak. Has anybody heard of these things? My intake has a threaded hole in it's base that I have plugged.
