Cobb In-Tank 4.5 Bar Fuel Pressure Regulator
INCREASED FUEL PRESSURE
The newer Subaru direct injection vehicles use a returnless fuel system with an in-tank fuel pressure regulator to control the low side fuel pressure. Cobb's replacement in-tank regulator raises the low side system pressure to 4.5bar which helps mitigate cavitation issues when the high-pressure fuel pump is operating at maximum flow. This is a direct replacement for the factory regulator.
