Aha... I believe I have an incorrect pressure cap. Hence the... "what is the point of this expansion tank"
That said, it sounds like the easiest thing to do is to keep the same system set up and move both tanks over to expansion tank area. That said, does anyone (supplier) make an brackets that are simple to install and hold both stock tanks.
Plus, to be sure, what is the specific expansion tank cap... vs. swirl tank cap. Stant cap numbers would be great.
