The guy lives in Detroit, it hasn't been hot enough in 3 months to cause gas in the tank to swell that much !!
The liquid won't expand much either way, it's the air/vapor in the tank that tries to expand, pushing out whatever is in the way.

An unvented fuel tank can push gas past the needle/seat when the temperature goes up. Plugged bleeds can lead to a siphon effect in the carburetor but would affect how it runs. Is it rich? The AFB/AVS carbs aren't supposed to do this (leak below float level). THIS; Had an issue w/a billet 850ish carb I built for Shane Studly and his stocker Mopar wagon. Ran great till he topped off the tank then the pressure in the tank literally crushed the ft. brass float(which I no longer use in builds) sticking the needle n seat flooding the car to the point of filling the crankcase w/gallons of gas. Solution, He added a vent to the filler neck and problem solved.....Especially important w/an elec. fuel pump....

Does it do it if the car isn't heat soaked? Sometimes the fuel will percolate after you shut it down as it has more time to absorb the heat, it can actually start to dribble out of the boosters, especially if the float is set on the high side.
