To simplify plumbing we fabricated our own metal hard-line for the BDE rails. If you are always after a clean and detail oriented engine bay, this is the product for you! This hard-line only works if running your BDE rails in a serial setup (i.e. one rail feeds the other). Features: • -6 AN fittings for a perfect fit • Stainless steel tubing (E85 compatible) • Bent downwards to clear the hood and complete the presentation • Hand polished for a mirror like finish • Proudly made in the USA!
