Carbureted Adjustable Regulator 5-10psi

The Aeromotive Carbureted Adjustable Regulator 5-10psi is a precision fuel pressure regulation solution designed for street and race carbureted engines that demand reliable, tunable fuel delivery. Built for serious enthusiasts and mechanics who understand that fuel pressure directly impacts jetting accuracy, cold-start performance, and overall engine responsiveness, this adjustable regulator lets you dial in the exact pressure your carb needs—whether you're running a stock restoration or a modified street engine. Unlike fixed-pressure alternatives, the adjustable design eliminates guesswork and costly trial-and-error tuning.

This in-line regulator features stainless steel construction with black and red anodized finish, delivering durability and corrosion resistance in engine bay environments. The unit accepts 6 AN female O-ring connections on both inlet and outlet, ensuring tight, leak-free seals that can handle sustained pressure cycles without degradation. A 1/8-inch NPT gauge port allows real-time pressure monitoring, letting you verify settings and diagnose fuel system issues on the fly. The 5–10 psi adjustment range is ideal for carbureted applications where excessive fuel pressure can flood bowls and compromise cold-start reliability, while insufficient pressure robs you of responsive throttle tip-in and mid-range punch.

Carburetor enthusiasts, classic car restorers, and vintage drag racers benefit most from this regulator's tunability and precision engineering. Installation is straightforward in both stock and custom fuel system layouts—plumb it between your fuel pump and carburetor inlet, connect a fuel pressure gauge to the NPT port, and adjust to match your carburetor's specifications. Weighing just 0.82 lbs and measuring 5.65 × 2.8 × 5.75 inches, it fits neatly in confined engine bays. Compatible with gasoline engines, this regulator is essential for anyone serious about carb tuning and consistent performance.
