I'm lazy. I like dispensed gas (diesel). A universal electric fuel pump and press down foot switch is great. We have carboy containers enclosed by wire mesh, 1/4" thick polypropylene. No rust. Pop open the vent cap and fill right after sunrise. Lowest humidity. The Kubota has a 15 gallon day tank. Junk settles to the bottom where it can be drained. The full carboy had overloaded Jesus' Mighty Max but not the replacement Toyota T100.
You talk about Nitrogen in another thread. Blasting out air and replacing it with Nitrogen would go a long way in preserving fuel in long-term storage.
