how does one go about safely hoarding gasoline?
You figure out how to do with other things what you used to do with gasoline.
Depends on how much and how long and how portable.
Most folks can readily carry a 5 gallon plastic or metal container
Few can carry a 10-15gallon container. They usually have wheels.
No one can easily move 55 gallons of any liquid including gasoline unless they have serious mechanical aids.
Net: 5 gallon containers are quite practical. Put Stabil or Sea Foam or any variety of stabilizers in the gas if you intend to store it.
Think about how you will get the gas to and into what needs it. Again I bet the 5 gallon containers are the best answer for most folks
NOT in the standard plastic 5 gallon gas containers. We’ve had 3 of them split at the seam and leak over the last 6 years.
55 gallon drum. Rotary pump with brass components.
Gasoline is a hard keep. It can go bad. That said, gas is better than no gas at all.
I use several 30 gallon metal drums and Marine Grade Stabil. I use the 5 gallon cans for moving the fuel to the vehicles or generators. Get a flexi funnel as the cans don’t pour well. I rotate my gas yearly-ish.

Re: storing gasoline. Can you use those 75 gallon plastic water tanks with in the cage thingy? I already have a 14-gal red can with wheels and the pumper attachment. But those are pricey. The white 75 gal in cage is cheaper.
