Aeromotive AER13113 Belt-Drive and Hex-Drive EFI Fuel Pressure Regulator

Ultra-High Flow EFI Regulator, adjustable from 40-100 PSI. Engineered for our Belt-Drive and Hex-Drive Fuel Pumps, the Belt Drive EFI Regulator is suitable for engines making up to 4,000 HP on gasoline and is compatible with gasoline and methanol. Perfect for any mechanically driven EFI fuel pump developing over 200 GPH at EFI pressure. Base pressure adjustable from 40-100 PSI. References Vacuum/Boost on a 1:1 ratio. Includes two boost line adapters, one barbed for rubber hose, the other for AN-04 braided line. (Prevents blow-off in high boost applications). Ports available for nitrous fuel supply, pressure gauges and transducers. (4) ORB-08 inlet ports, (1) ORB-10 inlet port and (1) ORB-10 return port. Single Spring Belt/Hex Drive EFI Regulator, 40-100 psi. Belt/Hex Drive EFI regulator; adjustable from 40-100 PSI; suitable for engines making up to 4000 HP; gas and alcohol compatable.

The Aeromotive AER13113 Belt-Drive and Hex-Drive EFI Fuel Pressure Regulator is designed for mechanically driven electronic fuel injection systems requiring high flow capacity and precise fuel pressure control. Its adjustable base pressure range of 40–100 PSI makes it suitable for high-performance gasoline and methanol applications, including engines producing up to 4,000 horsepower.

Engineered for belt-drive and hex-drive fuel pumps delivering more than 200 GPH at EFI pressure, this single-spring regulator maintains consistent fuel pressure under demanding conditions. It references manifold vacuum or boost pressure at a precise 1:1 ratio, helping maintain the correct fuel pressure across changing engine loads and boost levels. The included boost-line adapters support either rubber hose or AN-04 braided line connections and help prevent line blow-off in high-boost applications.

The Aeromotive AER13113 provides multiple ORB ports for flexible fuel-system installation, including dedicated provisions for fuel supply, return, nitrous fuel supply, pressure gauges, and pressure transducers. Its configuration supports professional racing and high-output street applications where reliable regulation and compatibility with mechanically driven EFI pumps are essential. This regulator is intended for EFI systems and is not approved for carbureted applications.

What's Included: Aeromotive AER13113 EFI regulator, one single regulator spring, one barbed boost-line adapter for rubber hose, and one AN-04 boost-line adapter for braided line.
