8AN Billet Aluminum Fuel Rails 5.2/5.9 Dodge Magnum fits the Hughes Airgap, M1-2-bbl, and M1 4-bbl intake manfiold, but you must specify which intake style you have. These custom rails utilize 8AN (3/4-16) o-ring fittings instead of NPT fittings which are prone to leaking. The mounting brackets are stainless steel which are stronger than aluminum.  Comes with a 6AN (9/16-18) o-ring port on the bottom of the driver's side fuel rail for the HiPoTek plug-and-play fitting kit. Satin finish.  Will not fit the OEM barrel intake manifold.  The Hughes Airgap, M1 2-bbl, and M1 4-bbl intake manifold each utilize different mounting tabs so please be sure to designate that option upon ordering.
