Took a lot of measuring and a couple of pieces of scrap, but eventually I figured how to make these with all the bends done with a bender on the bench before installation. Reminds me of those puzzles where you have to figure out how to turn two twisted nails to get them apart. You think it's not possible, but then you turn it in one very specific sequence and it just falls into place.

Specifically, they start as a straight tube 31" long, then from the selector outward, the bends are as follows (clocked in different but hopefully obvious directions) a 90* 2.5 inches from the end, then 3" to a 45*, then 17" to the next 90* then 3.5" for the final 90* out through the side wall.
Doing it this way makes them pretty, but will require that they be flared in place. I'm holding off on that and will likely take them out and put them on the shelf for safekeeping when it comes time to fit the wings.

EDIT- Hey idiot, it's me from the future. Don't take these out once they're in place. If you do, in about a year you will route wire bundles through those cover support ribs, then discover that after you unscrew the F-782B from the fwd face of the spar box, you can't get enough slack in the wiring to maneuver those really pretty fuel lines through.

You will then bend and tweak those lines for way to long trying to find a way to get them in there, then ultimately give up and make new ones in two chunks with a union ref. august 2022 log entries. also, it's bad form to have fuel above electric either where it can drip during a leak, or where an electrical fire can sent flames upward onto a fuel line. I've know this for years, so I built per print, but in the outboard corners, the wiring crosses in front of the fuel line then tucks underneath to go through the passthrough holes in the spar. I'm going to have to do chafe protection and standoffs in that area for my own peace of mind. I'm not so sure it was really any better in this case that just running full lines through the top hole. It certainly would have made the line fabrication and runs easier.
