It's a small check valve intended to close vent line to prevent fuel spillage in case of a "tip over". Should be located in the vent line down near the carbs, sometimes they get a bit of crud in them and get stuck causing the vapor lock problem you've been having. That's where that extra lenght of tubing comes into play, you can put the tubing over the vent outlet under the filler cap and reset the valve by blowing into the tubing.

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
