That goes back to my earlier question: Where is the reservoir open? Is there a vent somewhere I don't see? There's a plug that seals it where you add fluid. Should I be trying to run it without the plug to vent the air? I have it set up in my garage so the pump is the highest point in the system, so the air should be going to the pump now, but it doesn't seem to be leaving the lines, just running in circles around them... And thanks again for all the input! These kind of little issues are the ones that really get me angry.
