I have tested my pitot system using the EZ homemade system.  Works well with my
indicated AS right on the mark.  But I have a slow leak that I can not find.
Loses about 1 knot every 3 to 4 minutes. A little faster loss at higher manometer
pressures.  The leaks seems to stop when the manometer pressure gets to about
7.5 inches (105 Knots).  Is this acceptable?  Any advice on how to find leak--I
have "soapy bubble tested" all connections.  Thanks.  Jay rowe
