Avionics: MAP sensor connection

Since I am using GRT's avionics in my bird, I cannot use the kit's default provisions for the MAP sensor.

Here is an AN816-4D nipple attached to the port under cylinder 3 on the engine.  I used a VA-118-1 22" Brake Hose Assembly from Van's to bring that to the firewall.


I drilled a hole in the firewall between the two holes originally for Dynon/Garmin MAP sensors.  This hole has a VA-170 Restrictor Adapter (left), attached with an AN Spacer, 4D Washer and AN924-4D Bulkhead Nut (Right).


The GRT MAP sensor line is then connected.


Though not shown, the parts passing through the firewall were later sealed with fuel tank sealant.
