You are correct. The two 3/8" lines are fuel supply and return to the tanks, going out the side wall.
The smaller line is the brake line and it travels down the center tunnel, across the front of the spar, and then out the bottom. It is nestled into the corner of the gear leg support and the side wall longeron. It is tight to install but you only have to do it once. Did it this way to minimize the size of the leg fairing on the outside.
PM me and we can set up a call if you want to discuss in more detail.
