I slid the tubing through the holes. Takes 5 minutes. I thought there would be a lot of "pondering" time on this tubing installation for routing around the bellcrank and leaving slack for installing the pitot tube, but there really isn't. I tried running the tubing under the bellcrank, but I didn't like that. It bends around the bottom side of the bellcrank just fine and I can put an Adel clamp there to hold it.
I'll just leave this tubing full length for now. My intent is to minimize fittings and try to not have a disconnect at the wing/body join.
