It's not in the vent, it's in the filler tube itself, but maybe it will give someone an idea. I ended up with the filler tube out of a Saturn 4 door. In the vertical section just below the cap bung it has a liquid check valve in a captured plastic insert. It's not a ping-pong ball, bu it looks like one. If liquid comes up that far the ball floats up until it hits a small restriction and stops the liquid from being able to go any further.
Roll-over valves work the same way, but the ball is made of something heavy specifically so that it won't float. Which it needs to do for this use. Does Vapor Trapper sell the necessary floating check valve?
