  • The Cobb Subaru Fuel Rail Line Kit is designed to be used along with the Cobb Fuel Rail Kit. All lines are pre-assembled with double-swivel sport crimp style hose ends and ready for installation. Stainless reinforced PTFE line with black covering has a 3" minimum bend radius which allows for a straight forward installation when used as intended. With a 2500psi operating pressure and >10000psi burst pressure, these lines are incredibly robust.

    Upgrading your Subaru's fuel system is required in order to take advantage of airflow modifications such as intakes, exhausts, or turbochargers. The Cobb Fuel Rail Line Kit allows for increased fuel capacity and consistent performance at each injector. Pair this kit with the Cobb Fuel Rail Kit and Fuel Pressure Regulator Kit to build a complete system.
