I just replaced all the brake lines on my ‘99 standard that I bought new off the showroom floor. I pretty much rebuilt the whole bike and since I could still get the front OEM brake lines I went ahead and bought them. I also rebuilt my calipers with new upgraded SS pistons, seals, and speedbleeders.

Even if I live another 21 years I’m sure I won’t be riding anything other than a Rascal....

On my Rocket 3 I installed risers and needed to get longer brake lines. I did a lot of research and ended up buying HEL lines directly from HEL. They have a range of colors of both lines and fittings and they are top quality. I ordered 4” longer than stock and it worked out perfectly. I would recommend them highly, but Galfer and others also make great replacements.
Do what feels right to you and good luck...
