565 Series Pro Series Fuel Pressure Regulator

Description

FUELAB 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, this regulators hold no bounds. With a bypass capability over 5 GPM at 5 PSI, this regulator can handle blow through carbureted applications well over 1800 HP 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.

Select pressure range for you specific application. Note pressure range is in PSID- Pound per Square Inch Differential. Differential being the pressure ABOVE manifold pressure. Example if manifold is at 30psi boost, and regulator is set for 50PSID, actual fuel line pressure will be 80PSIG.
