Accelerator Pump Arm - Metal

The Holley Accelerator Pump Arm for metal 30 cc pumps is a precision-engineered component designed for carburetor tuning and fuel delivery optimization on high-performance engines. This steel arm with cadmium plating controls the accelerator pump mechanism, ensuring consistent fuel enrichment during throttle transitions—a critical factor in carburetor responsiveness and drivability across a wide RPM range.

Constructed from cadmium-plated steel, this OEM-specification arm resists corrosion while maintaining dimensional accuracy under repeated cycling. The 30 cc pump displacement rating indicates compatibility with Holley carburetors engineered for moderate to high-flow fuel delivery systems. The compact dimensions (5 x 2.1 x 7 inches) and minimal weight (0.09 lbs) facilitate straightforward installation and adjustment without affecting overall carburetor balance or manifold clearance.

This part is essential for anyone rebuilding or restoring a Holley carburetor system, whether for street performance, strip applications, or vintage vehicle restoration. Engine builders and carburetor technicians rely on OEM-equivalent pump arms to maintain factory-level fuel curve characteristics during acceleration. Holley's reputation for precision machining and material consistency makes this arm a reliable choice for carburetors requiring exact pump arm specifications.

Compatible with Holley 30 cc pump carburetors, this accelerator pump arm replacement ensures proper throttle response and smooth transitions between cruise and acceleration fueling modes. Whether you're tuning a street engine or maintaining a high-performance carburetor system, having the correct pump arm specification prevents erratic idle behavior and flat spots during acceleration.
