Qualitec CNC fuel pressure regulator is designed for high-performance EFI fuel systems where precise fuel pressure control, high flow capacity and reliable operation are essential. The regulator is suitable for turbocharged engines, supercharged engines and other motorsport applications where stable fuel pressure is required during idle, part throttle and full load.
The integrated 1:1 vacuum/boost reference ensures that fuel pressure follows intake manifold pressure, maintaining a constant pressure differential across the fuel injectors. This provides more accurate fuel delivery and stable engine operation, even under varying engine loads and boost levels.
Fuel pressure is adjustable from 30-100 PSI (2.07-6.89 bar), making the regulator suitable for both OEM and modified EFI fuel systems. The regulator is compatible with gasoline, E85 and alcohol-based racing fuels.
The CNC-machined billet aluminium body provides high strength, low weight and long service life. The included mounting bracket allows for secure and straightforward installation in the vehicle's fuel system.
This version is supplied complete with two 8 mm hose fittings and one AN6 ORB plug with a 1/8"-27 NPT thread. The plug can be used to install a fuel pressure gauge or fuel pressure sensor, making it easy to monitor and fine-tune fuel pressure.
