I am slowly finishing the rebuild of my wings and am in need of some advice for the Pitot tubing ends. The plan is to use a Garmin GAP26 heated AoA Pitot tube (Pitot will work with all EFIS manufacturers I am looking at) and leave the AoA tube open for possible future use. I do not have the fuselage yet and would like to run, bend, flare and final fit the tubing before I put the last wing skin on.
The problem: I do not know how much room I will end up with at the wing root during assembly to attach the Pitot tubing to the line from the fuselage. There are many pictures out there on the internet, but none found have helped. I have 1/4? OD Aluminum tubing in the wing for the Pitot tube; will not use flexible line until fuselage. In the picture below you can see a couple of options.
Option 1: After tubing exits the most inboard rib, 90 degree bend the line, flare and connect to fuselage line via union.
Option 2: Use one of the 2 unions shown in the picture, installed in the last rib. I would flare the line between the first 2 ribs and connect it there. The 90 degree union would keep things tight but will it be tight enough, or so tight that I will not be able to easily attach the line to the fuselage side which would require me to use the straight union?
On the inside of the wing, I am planning on bending the line 90 degrees aft where the B-nut and ferrule is, and terminating it with the 90 degree AN fitting shown in the picture below to connect to the Pitot tube. Any foreseen issues there? The pitot line in the picture is touching the bellcrank, but that will be bent to clear any chafing possibilities.
