yes, you are right. When I said that it would help, that would only be effective if you were sucking it down at a gallon a minute, run of the mill talks are under pressure, mostly because gas, does have a low point of vaporazation, sort of like boiling point. And it is also sort of like pop, shake it and it will give off gases. But the system is presureized to stop emmisions, and to a small degree to keep the aromatic solvents (read Octane) in the fuel, which is the first thing to boil off.
