Show original supplier description
The STM Evo 8/9 -6AN fuel feed and return kit with rail and regulator is designed to streamline your fuel system. It provides a direct-fit solution, including all necessary fittings, bolts, brackets, lines, and zip ties for a hassle-free installation. All components in this kit are engineered to be safe for use with corrosive race fuels, gasoline, and E85. The kit features a soft nylon braided hose that is less likely to scratch surfaces compared to stainless steel. It also comes with a silicone-filled fuel pressure gauge and a Fuelab regulator, offered in your choice of six colors (Black, Red, Blue, Purple, Gold, or Green). Vehicle Fitment: This kit is specifically designed for the 2003-2006 Mitsubishi Evolution VIII and IX models. Fitment with Evo 7 or JDM models is currently unconfirmed. Installation Notes: Ensure proper installation by using thread tape on the gauge and brass fitting, but avoid using thread tape on AN fittings. The blue O-rings and the bracket included in the Fuelab box are not needed for this installation.
