This section went amazingly fast, I think I completed it start to finish in a few hours which seems like the shortest section to date. I originally had a cheap screw clamp style flair tool that I used for the fuel tanks that I didn't particularly like, and instead invested in a rolo-flair tool for this section based on some research from the VAF forums. The result is a much cleaner looking flair, but after a few failed attempts I realized that it's critical to oil the cone of the tool first or it will leave a very rough surface finish.
Otherwise, I had a cheap harbor freight tube bending tool that worked just fine for this section. Using the provided measurements everything just dropped in and clamped on almost perfectly. I haven't found a way to pressure test it yet, and might just have to do that end-to-end once the tanks and engine are on.
