WOW , Larry, I did not know you were planning on getting all that good equipment.... You ARE my new BEST FRIEND
Yes , I am planning on keeping exact notes and taking the best pictures I can..... there are lots of 240s' out there... I think many people will benefit from upgrade info....
So I can just send my hose ends to YOU.... ? with specs on how long I need them ?

They make valves for some of these things... and I was thinking about installing Isolating valves on each end of my Reciever/dryer when I put it in.... if I did that on two parrellel Reciever /dryers I could alternate changing them out once a year on principle... cheap insurance to fight moisture...
