Compatibility and Fitment Information: This rail was designed for use with 48mm EV14 based injectors and 14mm o-rings. This is one of the most common and typical injector specifications currently available. Please contact us if you need help selecting injectors. This rail is NOT compatible with the original fuel injectors.

These rails are NOT compatible with the factory fuel lines.

Product Features:
  • Anodized 6061-T6 Billet Aluminum
  • Made in USA
  • Stainless and Aluminum Hardware
  • 1/2" Bore
  • -6 O-Ring Ports


Bottom Injector Adapters:
  • The original fuel injector bungs are too large for aftermarket fuel injectors. These bung adapters reduce the diameter of the bottom injector port to a suitable diameter for 14mm o-ring injectors. Our fuel rail height is set assuming these adapters are used.
6AN O-Ring Fittings:
  • Include a set of our high quality black aluminum 6AN o-ring port adapters for connecting your custom -6 fuel lines. Viton o-rings are supplied with the fittings.
