Coleman 425 conversion to Propane and pressure question
I have coleman 425 that burns with a yellow flame and covers all our pots and espresso machine with a fine layer of soot. While I was looking for a replacement generator on Amazon ( which I found at CNDTire) I found this contraption that converts the stove and allows it use 1 lbs propane bottle. https://www.amazon.ca/StanSport-185-Sta ...

Very cool now I don't have to buy a new stove as my wife wanted a modern stove like everyone else. This is great, best of both world I get the satisfaction of holding to a classic stove and my wife can't complain. The coleman stove can still run with the original coleman gas and tank or with the propane generator.

Now I want to take things up a notch. My local Costco fills up propane tanks for a fixed cost no matter the actual amount of propane that goes in the tank. So I want to burn off the left overs in my 20 lbs tanks with a contraption like this. :

I got the cable the allow to refill 1 Lbs tanks but rather, I would like to use the 20 Lbs tanks with coleman 425, as seen on this picture. I was almost good to test this out but I ran up against two female coleman style connectors.

I also think I need to another regulator to go from the 20 Lbs tank high pressure to the low pressure input on the Stansport device.
Have any of you here done this ? If so could you please share the details of what I am missing. I think this might be common setup on boats and RV's.
