Show original supplier description
The AAM Competition Fuel Return System - Basic is a direct bolt-on kit designed to convert the factory "return less" fuel system to a full return system for the Nissan 350Z and Infiniti G35. This system is engineered as a reliable, budget-friendly upgrade for those seeking the benefits of a Fuel Return System. This kit addresses limitations of the factory system, where the fuel pressure regulator is in-tank, lacks adjustability, and struggles to maintain consistent pressure with aftermarket pumps, especially under boost. The AAM Competition system replaces the factory regulator's control with a vacuum/boost-sensitive adjustable fuel pressure regulator, enabling precise adjustment of base fuel pressure and a proportional increase under boost. The system supports up to 450 rear-wheel horsepower (rwhp) and offers a wider range of adjustability for fuel pressure. It is particularly recommended for forced induction (supercharged or turbocharged) vehicles and those using large nitrous systems. Key features include its ability to increase fuel pressure with boost pressure, wider adjustability, and domestic manufacturing in the USA. It is compatible with 2003-2006 Nissan 350Z and 2003-2007 Infiniti G35 models.
