Aeromotive Extreme Flow EFI Fuel Pressure Regulator for Belt Drive and Hex Drive Fuel Pumps | 13137

Designed for high-horsepower EFI applications, the Extreme Flow EFI Fuel Pressure Regulator (P/N 13137) delivers precise, stable fuel control for belt-driven and hex-drive fuel pump systems. Built to support extreme flow demands, this regulator is ideal for race vehicles running gasoline, ethanol, alcohol, or diesel fuels.

Featuring dual ORB-12 inlet/outlet ports and an ORB-12 return port, this regulator is engineered to handle large-volume fuel delivery while maintaining accurate pressure regulation across a wide operating range. A massive 0.500-inch high-flow valve and seat allows it to support fuel pumps flowing between 7–32 GPM, making it suitable for serious performance and competition builds.

The compact, low-profile design incorporates dual internal springs to expand pressure capability without adding bulk or weight. The standard installed spring supports 30–75 PSI, while the included high-pressure spring extends the range up to 120 PSI, offering flexibility for both naturally aspirated and boosted EFI setups. Vacuum and boost reference are supported at a 1:1 ratio for consistent fuel pressure under varying load conditions.

Race Use Only: This product is not legal for sale or use on emission-controlled vehicles except when used on a dedicated race vehicle.
