AEM Adjustable Fuel Pressure Regulators


AEM Adjustable Fuel Pressure Regulator

AEM's Adjustable Fuel Pressure Regulators are capable of supporting enough fuel flow for engines up to 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 each regulator is tapped to accept a -6 AN or 9/16Ēx18 fittings.

  • Adjustable from 20 psi to maximum fuel pump capacity
  • Interchangeable discharge ports match regulator output to output of any fuel pump
