While we're on the subject, do you think running a vacuum pump would assist in any way with drain back? We do plan to run one after talking to Herb at Luhn. He suggested a GZ pump. What are your thoughts on that. Not that I'm looking at that as a bandaid. Just curious if the negative pressure would help to draw the air bubbles and oil into the pan.
