The FPR-D is a dual-function fuel system component combining a fully functional high-performance adjustable EFI fuel pressure regulator with a unique built-in fuel pulse damper. Works with any EFI fuel system and consolidates two critical components into one package.
Features adjustable pressure via a top-mounted knob (18.5–100+ psi), a stainless steel return orifice for laminar flow and pressure stability, and large 10AN ORB inlet/outlet ports. The integrated damper smooths fuel system noise from injector and pump pulsing, operating optimally at 40–105 psi base pressure. Includes a 360-degree swiveling vacuum reference port.
Note: Dampers cannot be used with mechanical fuel pumps or direct injection systems.
