If there was pressure build up which you would expect with vaporized gas (which has a higher degree of volume expansion with temperature change than a fluid does), it would burp air. To spew fluid gas, he must have filled it up to the rim at very cold temperatures, not consumed any fuel and let it get fairly hot.
I saw the same thing happen on a 4-wheeler, and his vent tube wasn't blocked. So I'm not sure how to explain in myself.
