I like this plumbing install better. After driving myself crazy trying to decide how to plumb the tanks, I opted to put off the final decision. I wanted to have the option to plumb all tanks together for simplicity but be able to isolate tanks with valves later if needed without having to open up the wing after paint, etc. This way each tank is plumbed seperate but will come together in a simple 4 way manifold. If I feel the need after flight testing, the manifold will be accessible to add valves if desired.
I continued the method of running the flexible metal fuel lines through a plastic line and rubber grommets for additional support and protection.
