Fuelab 57502-3 Mini Fuel Pressure Regulator 575 Series Carbureted Blocking Style 1-3 PSI

The Fuelab 57502-3 is a precision-engineered mini fuel pressure regulator from the 575 Series, designed specifically for carbureted applications. This compact blocking-style regulator delivers accurate fuel pressure control in the 1-3 PSI range, making it ideal for carbureted engines requiring low fuel pressure.

Key Features:

• Advanced poppet design provides smooth, precise fuel pressure regulation with no-creep performance
• Constructed from CNC-machined billet aluminum with military-spec Type II anodized finish for maximum durability
• Single -6AN inlet port and dual -6AN outlet ports for flexible fuel system plumbing
• Compatible with gasoline, diesel, methanol, and E85 ethanol fuels
• Maximum flow capacity of 50 GPH at 5 PSI inlet pressure
• Includes versatile mounting bracket with stainless steel hardware
• 1/8" NPT gauge port with plug for external pressure gauge monitoring
• 1/8" NPT pressure reference port with sintered bronze filter for atmospheric venting
• Fine thread pitch adjustment screw enables precise pressure tuning
• Regulation slope of 0.8 PSI per GPM for consistent performance
• Maximum inlet pressure rating of 45 PSI

The 575 Series mini regulators offer all the precision and reliability of Fuelab's larger 555 Series regulators while being 50 percent lighter and more compact. The blocking-style design is perfect for carbureted systems where fuel is regulated by restricting flow at the inlet. Intended for racing, off-road, and marine applications. Backed by Fuelab's limited lifetime warranty.
