The Fuel Press Reg Ultralight Carb 4-12psi 8AN/6AN from FUELAB FUEL SYSTEMS is a precision fuel pressure regulator designed specifically for carbureted engines and traditional fuel delivery systems. This ultralight design caters to engine builders, classic car restorers, and hot rod enthusiasts who require stable and adjustable fuel pressure without added weight.

This regulator provides an adjustable pressure range of 4–12 psi, which is suitable for most street and competition carburetors.

The ultralight construction minimizes unnecessary weight while maintaining robust internal porting and a reliable diaphragm design that resists fuel degradation.

This fuel pressure regulator is particularly beneficial for applications where weight is a critical factor, such as in high-revving engines or weight-sensitive builds. It fits compact engine bays with its dimensions of 4.9 x 2.85 x 5 inches, making it a practical choice for various carbureted powerplants, including street rods and vintage muscle cars.
