Hi Ralph,
    I am in Colorado on vacation so I don't have access to my work computer, manuals, etc but I think your description is correct except that the lower one nearest the cover (?) is for the Altitude sensor, not the TAS sensor.    You have the only version of the installation guide so the picture there should show the way.  

There should be no leak down on any of those ports but be aware that the MAX pressure on the TAS sensor is 2 psi.   More could damage it.

Well Tracy there are 3, the manual showing the one furtherest from the AQM cover is Pitot and the other 2 closer to the cover itself are Static, right?

There should be no leak down in the pitot plumbing.   You may have reversed the ports on the TAS sensor.   There are two on it, one for static and one for pitot.  The installation guide calls out 1/8" line for the sensors if using silicone tubing.   If the 5/32 line is leaking, try a small tie wrap the the sensors.
