began to work on the front sections of the fuel lines. route the tubing from the fuel selector to fittings, left and right and up. Still waiting for a few fittings for the back section. I've decided to go with rigid fuel line all the way to the fuel tank. When the wings was on, I marked the position of the tank fitting where I must exit the cabin. It will be easy to make that final connection when I'll put the wings back.
