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.
Just use a salt/ice bath to cool the little guy, and no venting is
required. If the big guy is in the sun, so much the better.

But remember - it is ILLEGAL to TRANSPORT a refilled cyl not
specifically designated as refillable.
