Well yes and no on the hose, I believe we are talking about the same hose, but it is not attached with screws, it is a 90 nipple that is pressed into the aluminum casing. I am putting my finger over the hose that is attached to that 90 angle nipple. It does go to a plastic box that is pretty close to right under the regulator. Is there a way for me to post a pic on here? maybe copy and paste? or doesnt that work
