Nuke Performance FPR100s is a compact, high-performance adjustable EFI fuel pressure regulator developed for high-performance street cars, motorsport, and other EFI fuel systems where precise fuel pressure control is essential. Its compact design makes the regulator ideal for installations with limited space without compromising flow capacity or pressure regulation accuracy.
The large internal diaphragm and optimized high-flow design ensure minimal pressure drop and a stable fuel supply 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 fuel injectors.
Fuel pressure is continuously adjustable from 30 to 100 PSI (2–7 bar). Adjustment is made using a precision ball-bearing mechanism that changes pressure by approximately 2 PSI per turn, allowing simple and accurate fine adjustment. The regulator is designed for EFI engines producing approximately 200–800 horsepower and is compatible with gasoline, E85, ethanol, and methanol.
FPR100s is CNC-machined from aluminum with anodized components and includes a stainless steel mounting bracket. The regulator features AN6 ORB ports, making it ideal for small to medium-sized EFI fuel systems where high precision and reliability are essential.
