That is a great way of doing it. When I convert to efi I will bring you the tank

First you have to wash them real well with a strong mix of some kind of soap and water.... Gas is an OIL based product -- so you can't just rinse with water like some morons try to do.... I use Simple Green -- and it's a strong solution. TWICE.
Then I use the SNIFF TEST.... Still smell gassy? Wash it again!
Then I rinse two or three times - until there's no soapy water....
Then -- Here's the trick! I put DRY ICE in the tank -- as it dissolves -- it turns into an inert gas -- Carbon Dioxide (CO2).... NO OXYGEN - NO IGNITION. It's the FUMES that kill ya! (Gas fumes and air). I displace all the air in the tank with the CO2.
I'd use a back gas of Argon... but that's expensive for a "home guy".... as you'd have to displace the air in a pretty large space. I can do this cheaply ---- AND I CAN SEE IT WORKING --- when I use Dry Ice.
