So, the previously mounted calipers did not have a 90 degree fitting installed yet, but simply a small nylon plug which kept things clean inside. I couldn't install the fitting due to interference with the metal bracket which the wheel fairing attaches to. I mistakenly loosened one affected nut before realizing it was wrong one to loosen. To fix that I had to remove the wheel to get to the bolt head and retorque it. Not fun. Got it done and removed the caliper to install the 90 degree fitting. I often wondered about using 1/4" 3003 tubing for gear leg lines, being that so many people are using special hoses, etc. I trusted an old sage on VAF who said he's had aluminum tubing and plastic brake lines for 30 years with no issues. Good enough for me. Fabbed the last line and installed it. One down. One to go.
