The Aeromotive AER13133 Pro Mod EFI Fuel Pressure Regulator is engineered for high-flow electronic fuel injection systems using belt-drive or hex-drive fuel pumps. Its expanded five-port body features one AN-10 inlet, four AN-08 outlets, and an AN-10 bypass return port, providing flexible plumbing options for demanding racing fuel systems.

A 0.500-inch high-flow valve and seat support fuel pumps capable of delivering 7 to 26 gallons per minute while maintaining precise fuel pressure control. Dual springs extend the regulator’s operating range without adding unnecessary bulk or weight. The standard spring is installed and supports a 30-75 PSI base fuel pressure range, while the included high-pressure spring supports 75-120 PSI.

The Aeromotive AER13133 supports both vacuum and boost reference at a 1:1 PSI ratio, helping maintain consistent fuel pressure as engine operating conditions change. This regulator is intended for automotive EFI applications and is not approved for carbureted systems. Professional installation and a compatible fuel system setup are recommended for proper performance.
