Description
The accelerator pump discharge nozzle is a critical component for precise fuel delivery during acceleration. A worn or incorrect nozzle diameter disrupts your carburetor’s air-fuel mixture at the moment you need it most, causing hesitation and flat spots. This genuine Holley 121-31 nozzle restores factory-spec performance and consistency across your fuel system.
