So I bought a bay window propane tank cheap and refurbished to new. All
works as far as I can tell.

Here is my issue. I bought a heater buddy extension, like 10 feet, that has
an acme valve in one side and a quick connect for my cook stove on the
other. No matter what I do o can't get it to work. I have slightly turned,
left, come back, turned more, etc.

I have tried turning quickly, slowly, very slowly, fast slow, connect one
side, then the other, etc. Nothing works...Nothing!

I have confirmed the gas is in there and is clear and flowing when I push
the plunger from the tank.

it seems to be my hoses. I have bought 2, one with regulator, one without,
neither work.

So, not sure what else can be done, at the end of my whits. Any
suggestions? Sure would be nice to ditch the 1 pounders.
