FUELAB Pressure Regulators

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 PSI to fuel injected applications up to 125 PSI. The 515 Series Fuel Pressure Regulator has a -6AN return port located on the bottom and the 525 Series has the same port in-line with the inlet port (not on the bottom) which allows for easy installation in extremely tight locations.
