I have already passed the point of no return on my fuel system but for all of you guys that are still contemplating 5 inch aluminum tubes in the outer wing. How about using a larger tube such as a 12 inch and compress it to fit the airfoil design. I would think that a plywood box could be built in the shape you need and start bending until it fits. Cap the ends and walla, A fuel cell with more capacity.
