Well found the leak on the lines to the Dynon from the Falcon. Checked the static lines as well. Redid the 1 line and took the stress off the plastic fittings.Dynon & Garmin pitot tubes have a drain hole on the bottom side.
If you have the single 1/4” tube from Vans, there should be no drain hole.
You’ll have to progressively test each section of the line till you find the culprit leak. Don’t forget to also check the ASI for internal or face leaks.
Good luck
