The XRSB850 is a double pumper design, which means it utilizes two separate fuel pumps to ensure consistent fuel delivery to the engine.

The XRSB850 also comes with a high-performance fuel pressure regulator, which can be adjusted to provide optimal fuel pressure for your specific engine and fuel system. The regulator is located on the top of the carburetor for easy access and adjustment.

The carburetor is equipped with a high-quality, billet throttle shaft and a 3/8-inch throttle cable. The throttle shaft is adjustable for idle and can be set up for various linkage configurations.

The XRSB850 is designed to be easy to tune and maintain. It comes with a set of factory tuned jets and needles to get you started, but can be easily adjusted to fine-tune the fuel mixture for your specific engine and operating conditions.

Overall, the ATM Innovations XRSB850 Carburetor is a high-performance, billet racing carburetor that is ideal for street and strip applications.
