Rob and Bob -

We also used those quick disconnects that Blue Mountain uses for all of  
our connections to the boxes in the panel. The company is Colder and they  
have a website that has all of the products. They even had a small  
diameter male fitting for those small tubes to the AOA box.

The manifold idea would even make it easier.

We also used several fittings of a line that McMaster Carr carries for  
some of the routing of the tubing and for static line drains. They use the  
1/4" OD nyloseal tubing and are push-in type that are used for fluids and  
gasses in the commercial world. I wish now that we had used them for all  
of the pitot and static system - instead of those darned compression  
fittings. They are easier to assemble and disassemble and are more  
compact. You can even get then in 45 degree or 90 degree swivels; which  
made the connections to the autopilot one heck of a lot easier. I have  
used the Colder quick disconnect fittings in the CO2 system in my beer  
refrigerator for years and have had no leaks.

Rob -  If you want the item numbers from Colder and McMaster Carr, let me  
know and I'll look them up in the parts file.

Cheers,

John
