Today, I made my final decision on how to route fuel lines. I cut holes through the bottom aft portion of the root rib and the #5 bulkhead at a 45 degree angle, and plan to run the fuel lines down and through the #5,6 bulkhead box. I spent the afternoon trying to do this in one piece, but wasn't happy with the outcome. At first, I only drilled 1/2 holes for the 45 degree angle, but will have to up size them and insert some type of line protection for the edges. More tomorrow.
