Fuel Pressure Regulator Adjustable 2-5psi

The Aeromotive Fuel Pressure Regulator Adjustable 2-5psi (MPN 13222) is a precision in-line fuel delivery control component designed for carbureted engines, mechanical fuel injection systems, and low-pressure applications where stable, adjustable fuel supply is critical. This ultra-low-pressure regulator bridges the gap between traditional carburetors and modern fuel management, making it essential for street rods, vintage restorations, and specialty vehicles running carburetor-based powerplants that require fuel pressure stability without the complexity of electronic feedback systems.

Built with clear anodized aluminum construction, this regulator features dual 6 AN female O-ring inlet and outlet ports, enabling seamless integration into existing fuel systems with industry-standard braided hose and fitting configurations. The adjustable range of 2 to 5 psi allows fine-tuning of fuel delivery to match specific carburetor float bowl requirements and fuel pump output, preventing overflow conditions and ensuring consistent atomization. The regulator's bypass valve design maintains pressure regulation under varying load conditions, protecting fuel system components from excessive pressure spikes while delivering reliable fuel flow across the entire operating RPM range.

This fuel pressure regulator is ideal for fuel system builders, hot rod enthusiasts, and restoration specialists working with gasoline, E85, or diesel fuel applications. The in-line design allows installation anywhere between the fuel tank and carburetor, offering flexibility in engine bay packaging and retrofit scenarios. Weighing just 0.75 lbs and measuring 4.85 x 2.7 x 6.45 inches, the compact footprint fits tight underhood spaces while maintaining durability and reliability through thousands of miles of spirited driving or daily use.
