Haven't figured out how to disconnect the pitot-static and vacuum lines -- I'll probably just pull them off somewhere and buy another pitot-static check when I put it back together. Due to the large number of instrument/etc that use pitot and static sources on our IV-P panels, I made manifolds out of Delrin and mounted them to the side of the radio stack frame. I then connected all instruments with nylon fittings and nylaflow tubing. This method provides only one pitot and one static line that needs to be disconnected to remove the "complete" panel. I used a "standard" nylon compression fitting for this. Another approach you might consider is to use the high quality nylon/stainless quick disconnect fittings used on oxygen systems. Mountain High, among others uses and can provide them, but I don't know the original source. BlueMountain Avionics (EFIS One) uses five of these to connect their computer to the various air sources. They are quick and easy to attach/disconnect, and have proven very sturdy and leak resistant to date. One caution with this approach--it would be very easy to reverse the connections upon re-installation. I'd mark them carefully, and run a ground check just to be sure... I'm still working on my "removable" panel, but we've finished Jim White's (N427JR) and it's flying. As Jim said yesterday while we were re-calibrating some of his instruments, "It's removeable, as we agreed to build it; but I certainly hope we don't have to ever really have to do it...." Based on our experience, I'd recommend that you also consider including some sub-panels that can be removed/pulled out for access to the back side of the main panel. On the IV, access over the top or from the bottom are just about impossible; I suspect this is the case for all models?
