Description
The accelerator pump is critical to fuel delivery response in any Holley carburetor, and a worn or damaged discharge nozzle will cause hesitation, flat spots, or inconsistent throttle response. This OEM Holley replacement nozzle restores proper fuel atomization during acceleration, ensuring your engine receives the precise fuel charge it demands. If you're rebuilding a Holley carb or troubleshooting off-idle performance, this is an essential component that's easy to overlook—but impossible to ignore once you drive with a fresh one installed.
