Default propane tank or fuel tank moisture while in storage

I have been told that you should fill your propane tank before parking for the winter, just wondering how many people do that and the fuel tank ?

I do keep the fuel tank filled to avoid moisture accumulating. Not sure that would be an issue with propane due to it being at high pressure unless it is completely empty.

If you end up with moisture in the propane tank, usually it is because the propane manufacture is not drying it correctly. Usually this does not happen.

What happens with the fuel tank is the air above the tank expands and contracts. each time it takes in more air (on a cold day or high pressure system in the weather) is moisture laden air enters the tank, and dry air leaves. With a full tank of fuel, it is much less than one cubic centimeter of air that can go in or out daily. Yet with a empty tank a cubic centimeter per day for a year can lead to some moisture getting into the tank.

Yes you can get moisture both in the propane tank and fuel tank. Our good friends that reside in the frozen tundra (MN) said you can have your propane line freeze due to it. So when that happens you can ask the propane company to add a can of dryer to your next fill.
