I must be missing something here.
I just can't grasp what you're talking about in relation to the images.
I know the ball valve is the one with the lever but I don't see the regulator. maybe you could point it out to me. (Sorry, really new to this)
If I get this through my head, Karl, could you give me a parts list of what you used for yours? Yours seems better than the one I was looking to build anyway.
