yea you can get get gas to boil by either raising the temperature of the fuel AND/OR lowering the pressure on it (put it in a vaccum)
In a carbed car during startup, the choke butterfly slams almost shut and makes a ton more vacuum( at the expense of airflow) and the fuel can get to boiling point even in the winter.
Manifold Vacuum. - in the intake manifold
Venturi Vacuum - between the throttle butterfly and the choke butterfly. High venturi vacuum boils gas IN the carburator, (and simultaneosly the vaccum sucks more gas from the jets for a Richer startup mix)
