About Holley

Holley is the legendary American carburetor and fuel-injection brand — over 100 years of induction history. From the iconic 4150 four-barrel to today's Sniper EFI conversions, Holley remains the choice for muscle car restorations, Pro Mod, and gasser builds.

Enhance Throttle Response with Holley Tube-Type Nozzles

The Holley .031 Accelerator Pump Discharge Nozzle is a critical component for any performance enthusiast looking to refine their carburetor's fuel delivery. Featuring a tube-type design, this nozzle directs fuel directly into the venturi, minimizing wall wetting and ensuring a crisp, immediate response when you hit the throttle. Perfect for Holley carburetors requiring a .031 orifice size.

Why Choose Holley Discharge Nozzles?

  • Optimized Atomization: Tube-type design ensures focused fuel spray patterns.
  • Consistent Performance: Manufactured to strict Holley tolerances for reliable flow.
  • Lightweight Aluminum: Durable, natural finish aluminum construction.
  • Versatile Application: Compatible with a wide range of Holley performance carburetors.
  • Complete Kit: Sold as a pair to ensure balanced fueling across your carburetor setup.

Fine-tuning your accelerator pump circuit is one of the most effective ways to eliminate "bog" or hesitation off the line. If your current setup is experiencing a lag, upgrading to these precision-machined nozzles can provide the necessary flow adjustment to get your engine back in the power band. Trust the quality of genuine Holley components available at GGCRACING.
