Garmin replaced my pitot tube because it did not pass the leak test; great service from Garmin! So I could redo the installation.
In the previous installation I used a 45 degrees bend for the tubes but this was not ideal because they were pretty close to the mounting bracket. I changed to 90 degrees bend.
I’m doubting wether I should create an extra bracket to fixate the connector to the spar…
I did a leak test of the manometer setup, the pitot system, the AOA system with the holes in the pitot closed with masking tape. Last I did a test with pitot and AOA connected; I’m happy it’s less than 10 kts in 1 minute starting at 150 kts:
