Aeromotive Belt Drive Pump EFI Regulator

The Aeromotive Belt Drive Pump EFI Regulator is an ultra-high flow electronic fuel injection regulator designed for high-performance applications. It features an adjustable pressure range from 40 to 100 PSI, making it suitable for engines producing up to 4,000 HP on gasoline and compatible with methanol. Engineered specifically for Belt-Drive and Hex-Drive Fuel Pumps, this regulator ensures precise fuel pressure control for mechanically driven EFI fuel systems developing over 200 GPH at EFI pressure. Constructed to prevent blow-off in high boost scenarios, it references vacuum and boost on a 1:1 ratio. The regulator includes two boost line adapters—one barbed for rubber hose and one for AN-04 braided line—along with multiple ports for nitrous fuel supply, pressure gauges, and transducers. It features four ORB-08 inlet ports, one ORB-10 inlet port, and one ORB-10 return port, providing versatile connection options for high-performance fuel systems.

Designed for use with belt-driven or hex-driven fuel pumps, this regulator is ideal for high-horsepower engines up to 4,000 HP on gasoline or methanol. It is compatible with a wide range of mechanically driven EFI fuel pumps that produce over 200 GPH at EFI pressure, making it suitable for racing, street performance, and other demanding applications. Installation involves mounting the regulator in-line with the fuel system, utilizing the included boost line adapters and ports for various fuel and boost control components. This regulator is a direct upgrade or replacement for existing high-flow EFI fuel systems, offering precise pressure regulation and boost referencing to optimize engine performance and reliability in high-boost or high-horsepower setups.
