This nozzle, manufactured by Holley Carburetor, is engineered for high performance and reliability, making it an ideal choice for both street and race applications.
The 121-40 Accelerator Pump Discharge Nozzle features a fine 130 micron atomizing orifice, which is about the size of a pinhead. This fine orifice produces a finely atomized fuel mist that improves fuel-air mixture distribution and combustion, resulting in quicker response, smoother idle, and improved fuel economy. Despite its small size, this orifice is capable of handling high flow rates, ensuring that the carburetor receives an ample fuel supply during acceleration.
The nozzle body is machined from strong and durable brass, providing excellent heat dissipation properties to protect against premature failure due to thermal stress. The brass body also exhibits superior resistance to common fuel solvents and detergents used in today's modern fuels. The nozzle comes with a high-quality, anodized aluminum tip. Anodizing is an electrochemical process that creates a hard wearing, corrosion-resistant coating on the aluminum tip. This coating helps prevent the tip from wearing out prematurely, securing optimum bore and tip alignment.
The bore diameter on the Holley 121-40 Accelerator Pump Discharge Nozzle is 0.060 inches and the tip diameter is 0.040 inches. This configuration offers effective atomization for gasoline-powered engines and allows for OEM or aftermarket carburetor compatibility. The fuel inlet diameter is 0.047 inches and is designed to connect seamlessly with a standardHolley accelerator pump distributor tube.
The Holley 121-40 Accelerator Pump Discharge Nozzle adheres to strict quality control standards. Each nozzle is thoroughly inspected during the manufacturing process, ensuring accuracy, consistency, and optimum functionality for all applications. The nozzle measures 0.75 inches in length and provides mounting threads that are compatible with Holley carburetors and most common accelerator pumps.
Replace the worn-out accelerator pump discharge nozzle with the new Holley 121-40 Accelerator Pump Discharge Nozzle to achieve optimal ignition system performance, smoother idling, and improved throttle response for your vehicle. Upgrade your carbureted fuel system to enjoy increased horsepower, torque, and fuel efficiency.
