Carbureted Bypass Regulator 3-60 psi

The Aeromotive Carbureted Bypass Regulator 3-60 psi is designed specifically for carbureted engines that require precise fuel pressure management in both high-performance and street applications. This regulator addresses the issue of inconsistent fuel delivery caused by fluctuations in pump output, vapor lock, or oversized fuel systems. It is ideal for modified small-block Chevys, classic muscle cars, and street rods with aggressive carburetor tuning.

The bypass design allows excess fuel to return to the tank while maintaining a constant pressure range of 3–60 psi. Its adjustable relief valve dynamically responds to fuel demand, preventing pressure spikes that can lead to flooding or hesitation. The regulator features a durable aluminum housing that fits compact engine bays without compromising flow capacity.

Carbureted engines, particularly those with upgraded fuel systems, benefit significantly from this regulator's precision control. Its design ensures cooler fuel return and mitigates heat soak during idle or stop-and-go traffic. Installation is straightforward, requiring minimal plumbing between the fuel pump and carburetor.
