Compact, 2-Port Body with dual ORB-12 inlet/outlet ports and one ORB-12 return port. 0.500? high-flow valve/seat, able to handle 7-32 GPM Fuel Pumps. Dual springs expand the range of operating pressure while maintaining a low profile regulator with reduced weight. Standard spring (installed) supports 30-75 PSI base fuel pressure. High Pressure spring (included) supports 75-120 PSI base fuel pressure. Supports vacuum and boost reference on a 1:1 ratio with PSI. Pro Mod EFI Gear Pump Regulator, 30-120 PSI, .500 Valve, (2) -12 inlets, (1) -12 return. Adjustable Regulator, 30-120 PSI, (2) -12 inlets, -12 return

The Aeromotive AER13137 Pro Mod EFI Gear Pump Regulator is an adjustable fuel pressure regulator designed for high-performance electronic fuel injection systems using belt-drive or hex-drive fuel pumps. Its compact two-port body features dual ORB-12 inlet ports and one ORB-12 return port, providing flexible fuel-system routing for demanding racing and performance applications.

A high-flow 0.500-inch valve and seat allow the regulator to support fuel pumps flowing from 7 to 32 gallons per minute. The installed standard spring supports a 30-75 PSI base fuel pressure range, while the included high-pressure spring expands adjustment capability to 75-120 PSI. The dual-spring design helps maintain accurate pressure control while keeping the regulator compact and lightweight.

The Aeromotive AER13137 supports both vacuum and boost reference at a 1:1 ratio with PSI, making it suitable for forced-induction EFI applications that require fuel pressure to track engine manifold pressure. Its dual inlet configuration and -12 return connection accommodate large-volume fuel systems. This regulator is intended for automotive performance use and is not approved for carbureted applications. Verify fuel-system compatibility, installation requirements, and applicable emissions regulations before use.
