I worked on what "should be" the last cabin to wing item that I needed to put into the fuselage that needed routing up the gear tower which is the pitot line. I have decided that I will have a union connecting the metal line in the wing with the plastic line that will snake through the fuselage to the instrument panel area.
I started by determining the routing for the line and then installed one more snap bushing where I wanted it to pass through the fuselage sidewall. Then I took the nylon hose and started winding it through the cockpit floor, the left gear tower and finally into the panel avionics area.
