The .042in Accelerator Pump Squirters - Tube Type from Advanced Engine Design are precision fuel delivery components designed for carbureted engine tuning and performance modification. These squirters are essential for anyone rebuilding or upgrading a carburetor, whether restoring a classic muscle car, optimizing a street engine, or fine-tuning a competition build.
The accelerator pump system delivers a controlled burst of fuel during throttle opening, preventing lean stumbles and ensuring crisp throttle response across all RPM ranges. Featuring a .042-inch orifice diameter, these tube-type squirters control fuel atomization and delivery volume during acceleration events, with the precise bore size being critical for performance.
Mechanics and engine builders select these squirters when diagnosing flat spots, hesitation, or surging on initial throttle application—symptoms indicating worn or incorrectly sized original components. The tube configuration allows for straightforward installation in standard pump passages, making them compatible with Holley, Edelbrock, and other popular four-barrel carburetor designs.
