Has anyone installed a Sorensen tank on a Cub with float fittings? From looking at pictures it seems that there would be an iterference issue. The Sorensen tanks appear to be as wide as the longerons with no cutouts for float fittings.
Check out the Landes tank, they have cut outs for the flying wires. If it was me I would go with the Landes for floats and save the Sorensen for wheels. Do you have the 60 or 90 gallon tank?
