learnt something about propane refilling

[ccbreder]

The modern 20 pound bottle valves prevent over filling. My propane dealer puts 20 pounds into the bottle. I have checked the weight of the bottles after I returned home. He is regulated and licensed so I think he is doing it right.
The reason to NOT have propane bottles in the vehicle is they all have a pressure/safety release valve that opens momentarily to relive gas pressure. The bottle is cool when filled and then is heated in the vehicle. If the bottle is on it's side, it will release liquid propane that immediately goes to gas. as above post, 11 to 1 if not more. What a fire ball!
I wonder what the 1 pound bottles could do in a sun heated car?

Worth repeating myself.

I am surprised kurb the place you had them refilled didn't say something about you transporting in the passenger compartment.  where I get mine refilled if they see you take them out of the passenger compartment they will not refill them.  highdesertranger

This may be their policy, but I don't think there is any basis in fact for it. Those tanks are regulated by the Department Of Transportation. As far as I know the DOT does not require anyone to have a pickup truck to transport. I believe they just state it must be secure, (as in can not move about. You might ask them what DOT regulation they are adhering to.

I have a Manchester 11 lb tank. It's short and squat. We need a smaller tank and could have lived with a 5 lb one. But this one is so cute! Yeah, who else would by a propane tank because it's cute?
