Back to work after a week of traveling in the 320.
Fabricated aluminium fuel line from rear seat aux tank to gear box fwd side. This line runs under the gear box and under the hydraulic lines.
This took an extraordinary amount of time since the rear seat bottom bulkhead and the aux tank had to be installed and uninstalled each time any change/bend/measurement had to be done. Finally got it perfect.
Made phenolic straps to hold hydraulic lines in proper relative position. Installed one, several more to go tomorrow.
