Zodiak Zenith 601 XLB pitot static leak check

Leak checking the tubing for the Pitot system in my Zenith 601. At first I did the whole system from the Pitot tube with the AOA port and the leak ports taped closed. 2nd test, I just checked the tubing from the probe to the display. Near 0 leakage if I bypass the pitot probe. Dynon instructions say even taping it off may not be leak proff. Challenge accepted!
