I am working on a gasser and intend to experiment with a single tank on the ground (27 inches away from the table top) to see if fuel can be pulled without a header tank. The purpose is to determine if pumper carbs will pull fuel to wing engines from a single center tank in the fuselage. The pumper carbs have a strong pull and there is no reason to believe that the concept will not work. As far as the tank shape is concerned multiple tanks can be plumbed in series to fit in about any confined space necessary.
