Well, I do know that pressure will dictate a phase change just the same as temperature will. I believe gas caps only vent one way, and that is simply to prevent the pressure from getting too high in the tank (this is why many states test the cap when doing an emissions test, to make sure it isn't venting at too low a pressure).
I absolutely don't understand why it would starve your motor. The pump is in the liquid, it isn't at the motor using suction. There could be total vacuum in the space above the liquid gasoline, and the fuel pump would still work just fine.
But yes, lol, I'm an "electrical" guy I suppose.
