Once I get to the windshield frame, I will tweak it to ensure it hugs the frame.
You can also use images of that line showing where it sits to get it bent right. I used a tube bender but the tiny tweaks you can do by hand - except for near the ends. Near the ends, one technique there is to slip on a brake line fitting (like one you took off that line) and use a box end to gently coax the tube to the direction you want, moving the nut as you go.
