there is a supplementary tank with a clunk, and this acts as a collector and a primary air tank. Result is there is never any air in the UAT on this model
feeds the 6 ounce hopper (not a UAT) and there is NEVER any air in the hopper after an aerobatic flight, any air stays in the intermadiate tank and the clunk always stays in the fuel.

Follow David's advice its based on sound flying experience. By having a full intermediate tank its possible to bunt, cobra, flick, neg G, inverted spin or any flight path you might fly. I wouldn't patent the drawing LOL thats just too complicated when the answer is so straight forward.
