515/525 Series
The 515/525 Series 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.
529 Series
These newly released 529 Series Regulaltors 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.
535/545 Series
The 535/545 Series Regulators have all the same great features as their 515/525 series, only smaller and weigh 50% less. These are a must have when space in the engine compartment is an issue.
555 Series
These Regulators are true precision instruments designed to regulate fuel. These units feature an advanced poppet design for smooth regulating capability. Fuelab has also incorporated a no-creep soft seat that's methanol and E85 compatible. It is adjustable from 4-12 PSI.
565 Series
The 565 Series Regulators have all of the same great features as their 515/525 Series except these are for extreme capacity. Utilizing a massive 1/2" 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). These regulators come in four different pressure ranges covering applications between 4 and 80 PSI.
