Okay, got everything figured out now. That top nipple doesn't do anything on my car. I turned it on and sprayed the fluid and nothing came out of that top nipple so I'll just leave that alone. WHY that fat hose was hooked up to the hard vacuum lines AND to that nipple is beyond me! Someone who owned the car before me has obviously done a lot of "jimmy rigging" to it. Thank you VERY much for your help, Scotty!!!!!! I'll be on my way to the parts store today to get the hose and T's and then hopefully I can have air coming out of the vents I want it to be coming out of...lol.
