Dont know where this idea of draining completely or having air in the tanks come from. One pound of liquid propane and gas mix is what you bought. Check Boyles law to get the pressure....which varies with the temperature. The vapour pressure stays in line with the temperature as long as there is ANY liquid propane...
Therse gauges that you add to your tank will give the same reading with a full tank or 1/4 tank.....
Make sure the 1lb tank is completely empty before you start as even a small amount of remaining propane liquid in the small tank will prevent it from filling. However, do not let the tank stand open (ie. don't put a torch on the tank and leave the valve open for an hour). Mixing air and propane inside the tank is very bad. You just want to release the pressure until there is no liquid left.[/QUOTE]
Think I understand your problem now....We are using a combination of gravity and pressure to fill the one pounders ( or five or ten pounders) When the donor tank is upside down, the valve discharges liquid propane and as long as the pressure in the donor tank is higher than the small tank it only takes a few seconds. The easy way to do this is pull the relief valve with needle nose pliers. If you do not crack the valve than you are just filling very slowly due to gravity.
As you release propane from the large tank, the remaining liquid cools which drops the pressure so you also have to keep the donor tank warmer than the small one.
Sure you can create a dangerous condition if you have a leaky valve. This is why we spit on any valve that we release, to check for bubbles, just like on your tires. If you trap propane in your trunk you could cause a problem when your trunk light switches on.....This is why you are not supposed to transport ANY fuel tanks in the trunk....but you seldom have a choice.
How...do tell... we are talkin gabout the 1lb tanks right. I go thru alot of these in the Truck camper as light with the coleman mini lantern that screws on top. I get my propane at COSTCO (20-30lbs tank) but I would be interested in how you fill the 1lb tanks?Quote:

Have the 20 upside down. Pull the relieve valve on the small tank open with needle nose pliers. Open the bulk tank valve until liquid propane spurts from the relief valve. Shut the valve then close the valve on the bulk tank. Caution though, liquid propane will burn (freeze) your skin. Always have lots of ventilation, or outdoors is best.Quote:

Think I will probably go with a 5 or 10 pound tank instead only costs about 2 - 5 bucks to fill.
Thats probably best, if the extra size and weight doesn't matter. I have a 5lb tank as well.Quote:

I run a 20ln tank in my ice hut to a medium size Mr Buddy heater which lasts 60 to 80 hrs run time. and a 5lb tank to a small mr buddy in my clam that's get 20 hrs out of.
The 5lb tank and a hose costs about 60$, and 4.25$ at pioneer for a refill. It pays for itself after about 10 1lb tanks or a couple weekends ice fishing. I've got a Rubbermaid the tank heater and hose mr buddy sits in !
It works awesome
Refilling is like walking on thin ice. Its not very smart, but you'll do it anyways. The real difference is that refilling a 1lber is illegal, and you put yourself in a liable position. I work with gaseous and liquid fuels, and compressed gases daily and do everything i can to admonish my self of any liabilities. Easier to sleep at night.
