I mis-spoke, you are of course correct ument panel mounted
computer unit. The static plumbing goes to the back of the autopilot tray.
That means any time you pull the KAP-140 out, like if it needs replacement
or adjustment, you're also breaking open the static system, which means you
have to do a static leak test. It's not a big deal as long as you never
need to pull the KAP140 out, but in my experience, you will. I haven't
found the STEC autopilots to have any better reliability, but at least
you're not forced to static leak check every time since they use a separate
sensor.

IIUC, the 172/182 KAP140 install (at least ones done at the factory)
have a second static port dedicated to the autopilot, it's not plumbed
into the port that feeds the standard (or ADC/backup instruments in
the case of the G1000) instruments.
