FUELAB® Fuel Pressure Regulators are true precision instruments. Our designs stand above others in reliability, flexibility and performance. Bypass, blocking, and electronic controlled regulators are all based on using the best quality components and proprietary materials to give our customers what they need – precise, stable fuel control. All FUELAB® regulators are machined from 6061-T6 billet aluminum, hand assembled, serialized, and come with a 2 year limited warranty. 

FUELAB® 515/525 Series Fuel Pressure Regulators are designed with performance and flexibility in mind. They accept port style and non-port style union fittings without interference. Several configurations are available, supporting carbureted applications as low as 1 PSID to fuel injected applications up to 125 PSID. The 515 Series Fuel Pressure Regulator has a -6AN return port located on the bottom. The 525 Series has its return port in-line with the inlet port (not on the bottom) which allows for easy installation in extremely tight locations.

FUELAB® 535/545 Series Fuel Pressure Regulators have all the same great features as our 515/525 series, only smaller and weigh 50% less.

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, 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.
