The Holley 4507-SA 4781 850 CFM Double Pumper Base Plate Complete is a high-performance fuel system component designed for racing applications. This base plate is a crucial part of Holley's double pumper carburetor setup, which is known for its ability to deliver large amounts of fuel to high-performance engines.

The base plate is made of heavy-duty, machined aluminum, ensuring rigidity and durability. It features a large, 850 CFM capacity, which can support the demands of even the most powerful engines. This makes it ideal for use in race cars, hot rods, and other high-performance vehicles.

The 4507-SA 4781 base plate is compatible with Holley 4150-series double pumper carburetors, and it includes provisions for installing an electric choke, electric fuel pump, and conveniently accessible fuel pressure regulator. The base plate also includes pre-drilled mounting holes for easy installation.

The double pumper design of this base plate allows for a more consistent fuel flow, which is essential for maintaining optimal engine performance. The design also enables the use of separate fuel bowls for each pump, ensuring that each piston only delivers fuel to its corresponding carburetor. This helps to prevent cross-flow issues commonly associated with single-pumper setups.

The 4507-SA 4781 850 CFM Double Pumper Base Plate Complete is a used product, meaning that it may show signs of wear or imperfections, but it has been thoroughly inspected and tested to ensure it functions correctly. It comes with a 1-year warranty, providing peace of mind for your purchase. Overall, this base plate is an excellent choice for anyone looking to upgrade their fuel system for high-performance applications.
