Subaru Legacy Fuel Rail

The Subaru Legacy Fuel Rail passes pressurized gasoline from the pump directly to the injectors, giving each cylinder a precise spray for smooth power and clean emissions. The early Legacy models featured TBI designs that incorporated a Fuel Rail within the TBI body, and one or two injectors sat atop the throttle plates which opened in response to powertrain computer solenoid actuation. With its transition to multiport systems, Subaru designated a unique Fuel Rail along the intake runners. This setup keeps fuel at steady pressure so that individual port injectors ahead of each valve can fire with shorter or longer pulse widths depending on sensor feedback. In recent generations, the common rail principle employed in diesel engines has been borrowed to feed quick response injectors with gasoline for gasoline direct injection. Thus, the Fuel Rail is able to cope with high pressures. The Fuel Rail is now able to withstand extreme pressures comparable to diesel setups. It thus feeds quick response injectors which now spray directly into the combustion chamber for better atomization and economy. Throughout these changes, the primary differences are pressure level, mounting location, and Fuel Rail injector support count, but each one keeps fuel delivery dependable for Subaru drivers who rely on their Legacy each day.

Disconnect electrical connectors from fuel injectors and vacuum hose from fuel pressure regulator. Disconnect fuel supply and return hoses from fuel rail.
