On top of all that, a buddy of mine just had a (used) tank refilled where the person didn't even open the purge vavle - just forced the gas in.
Doesn't seem like you would get a full load that way.
You are not forcing GAS in. LP is LIQUID PROPANE. So, you are filling with a Liquid. The 80 percent(purge?) valve is used as a secondary safety device when filling. The CORRECT and ONLY safe way to fill DOT tanks is by WEIGHT. You fill by weight and when the Tare weight matches the tank sticker weight, your tank is FULL to the safe liquid level. Now, you also have a OPD device, but THAT is also a 2nd/3rd safety device. If the 80 percent spews liquid you stop. If the tare/tank weight hits the mark you stop. IF you fail to follow this, then the OPD hopefully stops the fill. Also. if the tank was correctly purged on first/new fill, then there is NO WAY for AIR to get in the tank, so air in the tank is a none existent problem. Doug
