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.

Wanted to be sure the 5/32" ID silicon tube was connected to the right place in the AQM.  I configured a manometer to the steam gages in the front and rear cockpits
an observed about 3.3 inches of water gives a reading of 80 mph.  So far so good.  Then I tried to check what this pressure would do with the aqm (EM3) and found no change in
the near zero true air speed EM3 reading.  In fact there seems to be a bleed-off of pressure so I cannot hold a steady 3.3" pressure on the EM3 to measure anything.  Did I spend $ 28 to get this silicon tube for naught or am I confused about the one pitot and two static ports on this AQM?
 
And then again..the water temp was about 165 without the cowl, but on the latest ground  run the temp ran 188 degrees and climbing..gurss ya have to fly in to know...problem is the three pass19" X 20" X 2" radiator is some four inches below the steam chamber and water fill cap so at 17 inches of pressure indicated (EM3) coolent spewes out liberally from the radiator cap..  Can I add rubber washers to this cap or should I toss it away  and weld up that racing radiator cap location?  The water after radiator temp registered 30 degrees below the engine out water.. is this enough?
 
Wishing you all had problems so basic as mine!
