Racing fuel cans. Most racers use 100 octane racing fuel.
Many farm supply stores sell them.
Suggest you check with the hangar owner and/or local fire codes. Here at LVK we’re not allowed to store empty gas cans (unless filled with water or other inert substance), leave alone full ones.
Racing fuel cans are not DOT rated and technically are illegal to drive full on the road. Yes I know everyone does it, but the highway patrol can get you for it. Static is not an issue in my climate. I do recommend the flammable storage cabinets. I love mine and have one for my garage at the house. I recommend U-Line they have great customer service and overnight anything you buy. Their cabinet is the same used in any industrial application.
The metal safety gas cans are fantastic, I can use them and not spill a drop of gas, which has always been a frustration of mine with plastic gas cans.
