56504 High Flow Fuel Pressure Regulator

-10AN Inlets / MAX FLOW 1/2" Seat / EFI (40-80 PSID)

56504 High Flow Fuel Pressure Regulator

Item-detailsFUELAB® 565 Series Fuel Pressure Regulators have all of the same great features as our 515/525 Series except for extreme capacity. Utilizing a massive ½" return orifice and -10AN ports, these regulators hold no bounds. With the bypass capability over 5 GPM at 5 PSI, this new regulator can handle blow through carbureted applications well over 1800 H.P., and for EFI applications using belt driven fuel pumps; even further (with a flattened regulation slope). Regulator comes in four different pressure ranges covering applications between 4 and 80 PSI.

  • Two -10AN inlet ports and one -10AN return port
  • 1.75" sized diaphragm with 1/2" return orifice
  • Gasoline, diesel, methanol, and ethanol fuel compatible
