AEM's Honda/Acura fuel rail mounted adjustable fuel pressure regulator is capable of supporting enough fuel flow for engines in excess of 1000 horsepower. Our patented interchangeable discharge ports enable the regulator's output to match the output of ANY fuel pump.

AEM includes a custom barb fitting to accommodate the factory fuel hose, and the base of the regulator is tapped to accept a -6 AN fitting. Please note this is a fuel rail mounted FPR and not a stand alone universal FPR.
