Right above the wing interface fitting is the hole for the rudder cables so you gotta bend around that. The rest of the run is just trial and error, stretching, bending and cussing.
I made about 4 of these and I'm not sure the two keepers I have now are even keepers. I have only a couple small kinks. If this were a fuel line I would not allow any kinks. But a vent line can probably handle a slight kink. I'll revisit it later.
I put the Adel clamps on and clecoed them in place. I can see this line will be held pretty snug.
This run calls for a new hole in the top gussett. I made mine 2 5/8 aft of fire wall and 2 inches inboard from skin. This is a good location for clearance of the nut and still hides the tube under the gusset.
