I stumbled upon this thread about these guys doing a cross-Africa trip. Its pretty long, but worth the read.
One piece of interest was the use of the bags that wine-in-a-box comes in to store fuel.
Here is the link to the start of the thread, just keep clicking “continue” at the end. Warning: There is some National Geographic-type nudity. – Slinger
JWR Replies: This topic came up once before in SurvivalBlog. OBTW, it would be quite dangerous to store anything that is more flammable than waste vegetable oil (WVO) in a Mylar bag. Use only proper containers (such as DOT-approved fuel cans in the US) for transporting flammable liquid fuels.
