The highly-engineered AAM Competition 370Z Fuel Return System is the essential upgrade for improving the reliability of the 370Z fuel system.

The 370z factory fuel system is a returnless design with the fuel pressure regulator installed in the fuel tank. This regulator has no adjustment and is incapable of holding consistent fuel pressure with most aftermarket fuel pumps. The factory fuel pressure regulator is also unable to add fuel pressure under boost.

The AAM Competition HR Fuel Return System - Basic for the 2009+ 370Z is a direct bolt-on kit that converts the current factory “return less” fuel system to a full return fuel system. The 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.

With force induction 370Zs easily producing up to 500rwhp, this system is capable of supporting the demand for higher fuel pressure to efficiently run a car equipped with turbochargers, superchargers or nitrous.

Produced in the USA, our system includes the latest generation Aeromotive fuel pressure regulator, gauge, lines, fittings and hardware. Installs in 3-5 hours.
