The Aeromotive AER13304 adjustable regulator offers versatile fuel pressure regulation suitable for a wide range of automotive applications, including carbureted, EFI, and forced induction systems. Designed with a compact form factor that reduces overall size and weight by 33% compared to previous models, this regulator features larger -8AN ORB ports for increased flow capacity, making it ideal for high-performance setups. Its robust internal components, including an optimized diaphragm, poppet, spring, and bypass seat, ensure reliable and precise fuel pressure control across the entire 3-15 PSI range. The regulator's design eliminates common compromises found in other convertible models, providing consistent performance whether used with stock or modified induction systems.
Equipped with a 1/8-inch NPT gauge port and a 1:1 boost reference port, the Aeromotive AER13304 is compatible with forced induction applications, allowing for accurate monitoring and boost-based fuel regulation. Its compatibility with gasoline, ethanol, and alcohol fuels makes it suitable for various racing and performance vehicles. The regulator includes two -8AN inlet ports and one -8AN return port, along with a matching spring and poppet for a 0.313-inch bypass. Capable of handling flow rates up to 150 GPH with an AN-08 return line, it is compatible with pumps up to the Aeromotive A1000 series. The package includes a mounting bracket for easy installation, ensuring a secure fit in your vehicle's fuel system.
Whether adapting your carbureted engine to EFI or optimizing a forced induction setup, the Aeromotive AER13304 regulator provides dependable, application-specific fuel pressure regulation to support high-performance driving conditions.
