I'm wondering how this would work in a 1/4 scale gasser, mount the tanks in the wings (factory location) and run them to a header tank behind the firewall; the main reason this is attractive to me is to get the big tank out from under the instrument panel so it doesn't detract from a detailed cockpit. I realize it would be a pain to hook up fuel lines at the wing root in a manner reliable enough that they wouldn't leak. I guess the biggest problem would be finding tanks that would even fit in the wing.

Plan "B"--Does anybody make a tank that is more cubical; in other words, wider and taller than the typical tank, as well as shorter?. There's usually a lot of wasted room on either side of the tank when mounted behind the firewall. I'd like about 20 oz. capacity (US-41).
