This part was necessary for me to replace my stock handlebar with a buckhorn bar. I bought this as three separate units: the length of line with generic fittings at each end and two banjo fittings that are appropriate for my make and model bike. This is obviously not a Harley Davidson part. I bought it at an independent customizing shop (MDO Modern Cycles) in Gaithersburg, MD. These guys know what they are doing and have done this kind of thing once or twice, so I took their advice and got the three piece line. This was good because I was not exactly sure how long the new line needed to be, so I got a few lengths and then returned the ones I did not use. Awesome! I needed to drain the old brake fluid and replace it with new stuff when I was done. I highly recommend MityVac for the bleeding operation, but on the Sportster (or most other bike) it is not a big deal to do it the Bleeding brakes the old fashioned way. In fact that is exactly how I did it when I replaced my line as I did not yet own a MityVac.
