In between wrestling with the custom fuel lines, I also did a bit more on a couple other areas today.
I figured that the forward centre tunnel cover would be a lot easier to manage if it were in two pieces, so I cut it in half. This way I don't have to disconnect the fuel boost pump every time I need to get into the plumbing/wiring space.
I also did a bit more on the fuel boost pump cover. See the second picture below.
And finally, I worked on a better way to run my wiring conduit through the control stick linkages. I previously had rigid conduit here, formed to shape with my heat gun, but it wasn't so good. I've now shortened the rigid conduit and added a piece of flexible where it goes into the main spar. Heaps better.
