Ok, so , in english I have to hook up something to the  coarse outside
threads on my auto stop valve.Is this thing called the POL? Then from this,
I adapt down to the hose that will connect to the portable propane tank
fitting? Then I need this hose to go from this , to the portable tank? This
is 3 pieces.I have been looking at the web site of camper world and am
confused.I have not seen anything that will connect to these coarse auto
stop valve threads.If someone can itemize what is needed and point to a web
site (with part numbers)that sell them, I think many would like this(I
would). I am nieve about  RV LP and such and I am all thumbs here.  Does go
westy still sell that  fill adapter for the atuo stop valve? Have not seen
it in their cataloge since 2003.
