I just get rid of it. If you follow where the lines go, youll see one is the main feed for the rear brakes, the second line is coming from a T fitting on the front brakes. This is the aux feed, which puts more pressure in the back as the truck sits lower, indicating more weight. Just take the line and T fiting out and replace it with a barrel. I couldnt find any right away so I took off the line, cut it at the top of the fitting, welded it closed, and put it back in the T as a plug. Just clean the brake fluid out of it first so your weld isnt porous.
