I fstarted by installing the static pressure lines. I use the Van's kit, the instrcutions are rather vague and an article in the first 2006 RVATOR gives some more details.
The pressure port is a simple pop rivet, rather the riveting the rivet, I just took aout the mandrel and prosealed it to skin.



Here is the left inside view. The tubing going upwards goes to the right side pressure port, the one downwards to the left side and the bigger tubing goes forward to instruments.



Here the view of the tubing going through the seat bulkhead.



I then installed the rudder cables. The picture shows how they exit the fuselage, the plastic tubing is secured by a C-clamp.



So that it looks neater and more aerodynamic, I install small fairings (I think I bought them at Avery)



I then install the cable and supports for the shoulder harness.
