Routed out the wing rib holes (originally for 1/4 inch tubing) to fit my 3/8 inch tubing. Ran tubing from tip to LH wing skin elbow. Ran the lines to remain clear of the wing center line which will have a GII fuel stove pipe installed. Made a two ply laminate patch of the LH and RH wing tip closeout rib. These were for a different vent system than I am going to use. Tomorrow I will fill the holes from the outside with cabosil and put an additional two ply patch on the outside.
