COBB Tuning Subaru Fuel Rail Line Kits
COBB Tuning Subaru fuel rail line kits are incredibly robust. Offering 2,500 psi operating pressure and greater than 10,000 psi burst pressure, these kits allow for increased fuel capacity and consistent performance at each injector. Designed to be used along with COBB fuel rail kits, all lines are pre-assembled with double-swivel sport crimp-style hose ends; and the stainless reinforced PTFE line with black covering has a 3 in. minimum bend radius—which allows for a straightforward installation when used as intended. Upgrade your Subaru's fuel system with COBB fuel rail line kits, so you can take advantage of airflow modifications such as intakes, exhausts, or turbochargers.
