The marking on the wing was not as per manual! To clarify which is the right one I called Dennis B. and his advice to check before drilling with a piece of wire, as normally the marked one is right saved my day. Because the marked one was too close on the spar and I would have drilled into the wall of the tank!!!! For me the manual dimensions were the right once. Marking was 1/2" out! Gluing the fuel filler frame into the wing and also filling in all the wing leading edge, manufacturing wholes.
