RE: fuel cans
The attached pic shows a 2.5 Litre Winchester bottle. I believe that they're called "Boston bottle" in the US. Our solvent ether comes in these and most diesel users round the New South Wales area use them to store their diesel fuel.
The bottles are brown to limit the UV exposure of the contents. I've never heard of any concern about the formation of peroxides but you can buy 20 Litre metal tins of ether as well and mention of this may be in the MSDS for them.
A few years ago I bought six of these bottles at a local bottle supplier with twelve spare plastic caps for $50. The bottles seal very well and I've never heard anyone complain about leakage or evaporation problems.
