The .042in Accelerator Pump Squirters from Advanced Engine Design are precision fuel delivery components designed specifically for carburetor systems that require responsive throttle performance. These squirters are essential for anyone involved in rebuilding or tuning high-performance carburetors, whether for classic muscle cars, street engines, or racing applications.
The accelerator pump circuit plays a vital role in engine response by delivering an extra shot of fuel during throttle transitions, which helps prevent lean-out and stumbling during acceleration. With an orifice diameter of .042 inches, these squirters are engineered to control the precise fuel flow rate during pump discharge, directly impacting how quickly fuel reaches the engine when the throttle is engaged. Advanced Engine Design manufactures these components to exacting tolerances, ensuring consistent atomization and delivery across the full RPM range.
Mechanics and engine builders frequently specify .042in squirters for street and mild performance applications where balanced throttle response and drivability are essential. These squirters are compatible with both four-barrel and two-barrel carburetors, making them a versatile choice for various carburetor designs. If you're replacing worn or damaged pump nozzles or upgrading your carb calibration, these squirters will enhance your engine's performance.
