I just used a brand new 20# tank to fill a couple of one pound tanks.
Freezing the one pounder works to lower the contents of the empty, below atmospheric pressure, which is fine.
Try moving your set up closer the edge of the tailgate so you can tip it and the one lb. tank is at a 45 degree angle and filling is greater because the air pocket in the 1 # tanks moves right up near the top.

I want to run my motorcycle using the small tanks. Can I run a hose to the air box off a small regulator? I do not want to install venturi plates.

Most cylinders with float valves will still work with this. The float valves usually only stop the cylinder from being overfilled, but won't stop liquid propane from coming out when the cylinder is upside down.

We used to refill 100 lb. tanks for use in the oilfield from a bulk tank every few days, and I can only imagine how much it would have cost to buy new ones each time. The only problem I ever had refilling was not getting a connection tight enough and the resultant leak then gave me an instant frostbitten finger.
Thanks for the great info!
No longer works. Manufacturers are putting a float valve in the BBQ propane tanks, when they are upside down, they will not allow propane to escape. If you want to do this, you will have to use some other tank than a 17 pound tank (BBQ Grill size)

@edpleasure Thanks, I don't know when they did this, I have a tank less than 2 years old and it works. Anyone can check their tank by tipping it upside down and briefly open the valve if propane comes out, it should work....Be careful of course, and do it outside...This is value added to older tanks now...

I just purchased an adapter to my 20 gallon propane tank...I tried using this weekend on the lake but wasn't successful...is it because the 20 gallon tank too cold or is there something else that I'm not doing correctly...

@thaolover Since with this method we are not using a pump, we use temperature differential as the means to get a good fill. The large tank should be warmer than the small cylinders. Tank temperature room temp 70 - 80 deg F (don't heat it or put in sun) the cylinders can be put in refrigerator or freezer to cool. Leave connected a couple minutes.

the problem for us up here, if I understand the law right is that refilled small cylinders are illegal to transport :( , but I don't know how they could ever tell.

@landlockedviking Hey my lips are sealed, who would know, haha? Uhhh, I don't advocate breaking the law. There is nothing you do that would indicate they were refilled, I do check mine for leaks. Thanks for watching!!
