Continued working the fitment of the fuel lines, pitot/static lines, and light/fuel sender wiring into the left vertical channel. I previously tried to cram all the above into a piece of 3/4" wire loom, and nothing worked well.
This time, I wrapped the braided fuel line in a length of 1/2" loom, and used another section of 1/2" loom to hold the pitot-static and wires. Seems to fit well, and the lines pull easily in the loom, so no pinching.
