[@Treue] I mean, you could do it, sure. Just be prepared to wait around for a long long time, cuz that's a big fuel tank and you need a lot of fuel. Maybe start the siphon in the evening and have someone check on it overnight to make sure it's still going. [@Gunther] Make sure that the tank takes standard gasoline. Some of them use diesel fuel, and that's gonna be thougher to find, though plausibly in better supply because it's not as popular. EDIT: never mind, checked the journal.
