I decided to redo the air pressure tubing at the front of the cockpit after my earlier try revealed interferences with the rudder pedals. There are two systems to deal with. First there are through-hull static ports on each side that need to be cross connected to each other and also run to the Airs Speed Indicator (ASI) analog dial mounted in the dash board and to the Dynon ADAHRS module. Then there is the tubing running from the Pitot/AOA sensor out on the port wing, that also has to be run to the ASI and to the ADAHRS. My tubing came with my wiring harness along with some plastic 'stick in" connectors. I decided to purchase some "push in to connect" quick disconnect fittings in the forms of ells, tees, straight connectors, etc as they looked more secure and were easier to use.
