Qualitec fuel pressure regulator 2x AN8 ORB / 1x AN6 ORB red/silver

This adjustable EFI fuel pressure regulator is designed for high-performance EFI fuel systems where precise fuel pressure control is essential for both performance and reliability. The regulator is suitable for performance, motorsport, drag racing, and circuit racing applications with medium to high engine output, ensuring a stable fuel supply even under demanding conditions.

The internal high-flow bypass design provides fast and accurate fuel pressure regulation, allowing the fuel system to deliver consistent fuel flow during idle, part throttle, and full load. The integrated 1:1 vacuum/boost reference ensures that fuel pressure follows manifold pressure, maintaining a constant pressure differential across the injectors under both vacuum and boost.

Fuel pressure is adjustable from 40 to 75 PSI, making the regulator suitable for a wide range of EFI fuel systems. It is compatible with gasoline and alcohol-based fuels, including E85, making it an excellent choice for both performance vehicles and professional motorsport applications.

The regulator features two AN8 ORB inlets and one AN6 ORB return port, providing excellent flexibility for installation with both single and dual fuel rails as well as high-flow EFI fuel systems. The integrated 1/8" NPT port allows a fuel pressure gauge to be installed for quick pressure checks and precise adjustment during setup and tuning.

The compact aluminum housing is designed for demanding motorsport applications where high flow capacity, precise regulation, and long service life are essential. Its robust construction ensures stable operation even under high loads and prolonged use.
