Flame King 16.4 oz refill

[Winnie 2000]

Hello all, just wondering if anyone has filled the Flame King 16.4oz refillable LP cylinders from their horizontal LP tank on their MH. Flame King only has instructions for filling from a small gas grill cylinder turning it upside down. I know LP is a liquid and Flame Kings method would probably work quicker but the difference in pressure between the tanks I would think would allow the LP to flow into the 16.4 tank. Any thoughts.

The pressure would equalize quickly and stop flowing long before you moved much liquid.
If your small tank has a bleeder valve, you would just be letting gas out as it came in. That's why the 20 lb tank needs to be inverted. Gets the liquid to the valve.

If you have a liquid line on the RV tank then you would have a chance.
