Decided to mimic Steve W's pitot on his Patrol. He uses a little 3/16” tube mounted onto a bulkhead AN union. Aluminum tube is fitted on the front for pitot tube and on the back (inside the wing) there is a short piece of 3/16 tube and then the nylon pitot line to the instrument slips tightly overtop with a bit of sealant. I finished the hatch by the strut and mounted it in the centre of the hatch.
