Transferring propane from old tank to new one

[LightningCamaroGuy]

Is there any way to do this. I recently switched propane companies, and the old company hasn't come to get their tank back yet. Right now both tanks have about 30% propane in them, and I'd love to keep the old gas I paid for. When they installed my new tank yesterday they wouldn't/couldn't take the gas out the old one and adf it to the new one. 28-30% full in a 325 gallon tank is around 100 gallons or there about.?.? That's around $300 right now.

Here are pictures so that yçall don't think I'm asking, looking to steal propane or anything.

When I switched to geothermal they took the propane from the tank at the house and put it in the one at the shop. I think it takes a propane truck to do it.

Is the old company willing to give you credit for the propane that's still in the old tank?

They used a transfer pump to move old propane from my above tank into my new underground tank. Easy peasy.

The "proper" way to do it is for a propane truck to pump it out of the tank into the truck and then from the truck into the new tank.
The old way was a "thief" hose that attaches to the liquid draw line of the old tank and the fill port of the new tank. They will transfer fluid until the pressures, pressure not liquid levels are equal. Then the vent to atmosphere can be opened on the tank being filled and the pressure will transfer liquid over.

My company had a electric pump on their rig, never went into truck

When I had a natural gas line run to the house (1600’) I sold my propane tank to the propane company. They sucked the propane into the truck to empty the tank and it was metered. Then another truck came to load the tank. We agreed on a price per gallon for the fuel and a price for the tank. They ended up paying me $800, most of which was for the tank. But my point is that yes they can empty a propane tank and meter the fuel as it comes from the tank.

The company I used to work for could syphon it out, but the truck had to backup no less than 6' from the old tank.

A short hose was connected to a wye shaped siphon valve and the valve was connected to the tank and the other end of the hose was connected to the fill port on the truck.

The pump hose was connected to the third end of the siphon valve and the pump was started.

This vacuum would siphon the propane out of the tank and into the truck.

I'm hearing mix, but not positive feedback on them fully reimbursing you for gas in the tank. That got new ownership a few years back, and the new people seem to not be so good. I'm not the only one I know of who is on the outs with them, switching to someone else. They're just not pleasant to deal with.

Someone was saying that gas companies aren't allowed to take gas out of another copies tank, but IDK for sure.
