The plans call for prosealing the top of the tank filler neck to the fuselage. I know that removing the tank will probably be an annual affair. The problem is that the fuel return line extends about 2 1/2" above the tank filler flange. To me, it looks like you would have to remove the filler neck with the tank, rather than merely loosening the rubber collar and sliding it out. Has anyone thought about cutting the return line off, flush with the top of the tank flange? Now, removing the tank would be a piece of cake.
