Slowly and methidically isolated each instrument to test. Started directly with AHARS 2 on co-pilot side. Once I got the right technique to do the leak test it was fine. Used a dental syringe and a piece of nylaflo. NO fittings...less is better.
Found 2 nylon nuts loose at pitot connection to AP tray. The nuts were visibly not tight. Dah. Not sure if I did that or if it came back from Aerotronics that way.
I am good all the way out to the left wing tip now, but then big fail. Either the compression fittings to the pitot mast tube, or the GAP 26 itself. Starting fooling with the old Aero probe, but I am not sure of the fittings and I was tired of fooling with it all for the day
AC 43-13 standard is less than 10 knots in 1 minutes. I'm at< 2 knots with the whole system out to the wing tip.
added a Safear union in tip to test/install easier
