Fuel Press Reg Mini Carb 25-65psi 6AN/6AN

The Fuel Press Reg Mini Carb 25-65psi 6AN/6AN from FUELAB Fuel Systems is a compact fuel pressure regulator engineered for carburetor-fed performance vehicles and classic hot rods. Built for enthusiasts who demand precise fuel delivery control without sacrificing under-hood real estate, this mini regulator addresses a critical need: maintaining stable fuel pressure across varying engine loads and RPM ranges. Whether you're tuning a street engine or managing fuel delivery on a lightly modified build, this compact design delivers the pressure stability carbureted engines require while fitting tight engine bays where full-size regulators simply won't work.

This regulator features a fully adjustable pressure range of 25–65 psi, allowing you to dial in the exact fuel pressure your carburetor demands for optimal atomization and metering. The dual 6AN inlet and outlet ports provide excellent flow capacity while accepting standard -6 hose fittings, eliminating the need for adapters and reducing leak points in your fuel system. The pressure-compensated design automatically adjusts fuel bypass flow based on system demand, preventing fuel starvation at high RPM and eliminating excess pressure that can flood carburetors at idle. The compact form factor—measuring just 4.9 x 2.9 x 5.1 inches—fits easily in tight spaces without requiring extensive re-plumbing or custom brackets.

This FUELAB regulator is ideal for vintage muscle car restores, street rod builds, and any carburetor application where space or traditional fuel pressure control is challenging. Its low weight of just 0.64 lbs makes it a bolt-and-bolt installation without adding significant mass. Install it between your fuel pump and carburetor, set your desired pressure with the adjustment screw, and enjoy rock-solid fuel delivery across your entire RPM band. The 6AN ports work seamlessly with modern fuel line standards, ensuring compatibility with contemporary fuel system components while maintaining the vintage aesthetic of classic carbureted engines.
