When a liquid changes to a gas in a sealed container, the pressure will stabilize based on temperature. You could have a few drops of liquid or a quart and the pressure would be the same.

Of course. That is basic gas properties. Should I go to autozone get a vacuum pump and gauges and do it myself or have it done?
