A direct bolt-on kit that converts the current factory “return less” fuel system to a full return fuel system. The “return less” system from the factory offers minimal adjustment to the amount of fuel the engine can receive.
This system is a must have for any forced induction supercharged or turbocharged 350Z HR/370Z because the AAM Competition Fuel Return System removes the factory regulator’s control of fuel pressure and replaces the control with a vacuum/boost sensitive adjustable fuel pressure regulator. This allows you to adjust both the level of base fuel pressure and increase fuel pressure under boost.
