with the wiring is easy
If your using the stuff from safe-air instead of aluminum, why not just route it along wth the wiring... Through the spar, along the front of the center section, and up the center floor channel. You probably already have a grommet to dedicate to the pitot line on the front of the center section.
The pitot static kit from SafeAir is great. I ripped out my aluminum lines because their kit is just a better design: lighter, less likely to leak, easier to route.
