Fuelab 565 Series Fuel Pressure Regulator

Fuelab 565 Series Fuel Pressure Regulators share the same great features as the 515/525 Series yet offer extreme capacity thanks to a massive 1/2″ return orifice and -10AN ports. With a bypass capability of more than 5 gpm at 5 psi, this billet aluminum regulator can handle blow-through carbureted applications well over 1800 HP and even higher EFI applications that use belt-driven fuel pumps with a flattened regulation slope.
