10. The 18-inch braided stainless steel flex lines used on our Valiant are not part of the kit, but can be ordered separately from Wilwood as PN 220-8307 ($66.61, pair). They replace the stock rubber lines, and include a -3AN fitting adapter that attaches to the end of your factory hard lines. Note that the Wilwood system does not use a banjo fitting and copper crush washer, which can result in a dangerous loss of fluid and pressure if not designed or installed correctly. The Wilwood lines screw directly into the caliper, eliminating any possibility of sudden pressure loss.
