I ran my pitot lines down the rear spar and then loop it around the end of the wing and down in between the ribs to the pitot tube.
Lines down the spar were encased in a corrugated conduit, while the lines through the ribs were placed in a wood fixture glued into each spar and where there was no rib I tied the tubes to a standoff with zip ties.
Each of these connection points can be seen in the attached pictures.
The pitot tubing enters into the cabin at the rear spar connection then travels down behind the seat to the floor and then enters the tunnel area under the center console and up to under the dash area to connect with the instruments. This line is then hidden in the upholstery wrap that goes around the the wiring, fuel and pitot tubing behind the pilots head.
