This will not work with the new OPD valves because they are designed to NOT
release liquid!
To refill a standard lantern/torch size propane tank:
Invert a large tank (40 # or larger with no OPD) on a bench so you are
gravity feeding only liquid propane.
Use a tire valve wrench on a long handle to open the relief valve on the
smaller container. It is a standard Schrader type valve on one side of the
top that extends about 2" down into the tank.
Set the small container vertical and brace in position.
Connect the refilling hose.
Open the valve on the large tank.
Fill until liquid starts coming out the relief valve.
Close the large tank valve then holding the wrench with a gloved hand close
the relief valve
Remove the fill hose.

The small tank will be about 80% full which is the original safe fill level
to allow for thermal expansion.

Well I suckered for it. Bought the HF brass fitting whereby you can
transfer some propane from your barbeque type bottle to your hand held
flask.

Tried it, BUT, it only fills the flask to about 10%±. I'm just guessing
by weight.
The flask in this instance does have a shrader valve on it and I could
pull a vacuum prior to filling. Would this be of great help? If I
inverted the pair of tanks would I be able to get liquid into the tank? I
would be happy if I could get near the 50% mark. Son-in-law is going
through a lot of this stuff doing candle art.

Advice appreciated. BTW, did give it about a half hour. It does fill,
but not much.
