Carburetor Accelerator Pump

Description

Walker Products Carburetor Accelerator Pumps are precision-engineered OE Replacement components designed to restore crisp throttle response and smooth acceleration in carbureted engines. During rapid throttle transitions, the accelerator pump delivers a precisely timed fuel shot to prevent stumble, hesitation, or bogging. Over time, the diaphragm and seals can wear or degrade—especially when exposed to modern ethanol-blended fuels—leading to poor performance or hard starting. Each Walker accelerator pump is manufactured to match OE dimensions, stroke travel, and output volume, ensuring compatibility with factory carburetor specifications. Constructed using high-quality, fuel-resistant materials, including ethanol-safe diaphragms and corrosion-resistant internals, these pumps are built for long-lasting reliability. Whether performing routine maintenance, tuning for performance, or restoring a vintage engine, Walker Carburetor Accelerator Pumps provide a cost-effective solution to eliminate throttle lag, improve engine response, and maintain drivability in classic and performance vehicles.
