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® 529 Series Electronic Fuel Pressure Regulators – Take the guesswork out of fuel delivery. Set the pressure mechanically like a traditional bypass regulator, then let the electronic regulator’s demand based speed control take care of the rest! True pump control is finally achievable and easy to install.
