The Holley Ultra Series carburetors are known for their smooth idle and excellent vacuum secondary operation, which is crucial for maintaining consistent power throughout the entire RPM range.

The design of the Ultra Double Pumper carburetor includes a unique accelerator pump design, which provides rapid fuel delivery to the throttle bodies during rapid acceleration. The accelerator pump is controlled by a vacuum-operated diaphragm, ensuring precise fuel delivery in response to driver input.

The Holley FR-7685-0HB 850 CFM Ultra Double Pumper Carburetor is constructed of high-quality materials, ensuring durability and reliability. The carburetor body is made of aluminum, and the float bowls are constructed of glass-filled nylon. The carburetor also includes a billet aluminum linkage bracket and a brass fuel bowl gasket.

This Holley carburetor comes with a factory-set base circuit, making installation straightforward and hassle-free. It is essential to note that the optimal jetting and needle setup will depend on the specific engine application. Holley offers a range of jet kits and needle configurations to help find the perfect setup for your engine.

In conclusion, the Holley FR-7685-0HB 850 CFM Ultra Double Pumper Carburetor is a high-performance, reliable, and durable addition to any hot rod or custom project.
