Fuelab 52901-6 Electronic Adjustable Fuel Pressure Regulator - 529 Series

The Fuelab 529 Series Electronic Adjustable Fuel Pressure Regulator represents a breakthrough in fuel system management for street and strip applications. Designed to work seamlessly with Fuelab's Prodigy line of fuel pumps, this innovative regulator actively reduces heat buildup and eliminates vapor lock conditions that plague high-performance vehicles.

Advanced Electronic Control:

Unlike traditional bypass-style regulators, the 529 series communicates directly with Prodigy fuel pumps to intelligently control return line flow rate. This demand-based approach means the pump only works as hard as needed, dramatically reducing heat generation in the fuel system while improving efficiency and reliability.

Key Features:

• Electronic signal-based regulation works directly with Fuelab Prodigy pumps
• Demand-based fuel delivery system minimizes heat buildup
• Prevents vapor lock in street/strip applications
• Super-fast response time for precise fuel pressure control
• Independent system operation—no external calibration required
• Simple installation with plug-and-play functionality
• Reduces fuel pump workload and extends component life

The 529 series regulator is ideal for performance enthusiasts who demand consistent fuel pressure without the heat-related issues common in traditional systems. Its intelligent design makes true pump control finally achievable without complex tuning or calibration procedures.
