The Aeromotive Part #aer13303 is a versatile and high-performance adjustable fuel regulator designed for a wide range of automotive applications, including carbureted, EFI, and forced induction systems. Constructed with larger -08 AN ORB inlet, outlet, and return ports, this regulator supports increased fuel flow, making it suitable for engines demanding up to 150 GPH with an AN-08 return line. Its compact design reduces size and weight by approximately 33% compared to previous models, ensuring easier installation and less space consumption without compromising performance. The internal components, including the diaphragm, poppet, spring, and bypass seat, are optimized for responsiveness and durability, providing reliable fuel pressure regulation across the adjustable range of 35 to 75 PSI. This wide adjustment range accommodates various fuel system setups, whether you are tuning for maximum power or efficiency.
