FTDK - a small generator is technically a DG, although if you are flying privately, you're generally OK as per the aforementioned regs. UN 3166 off the top of my head "engines, internal combustion." I write it a bit.
There are some operations in the world that fly fuel around all the time without incident. Sometimes in 44g drums, sometimes in jerry cans.
A quick look at the Alaskan DG regs might open a few eyes in this country. In fact there are a lot of things in Alaskan aviation that open eyes.
