50cc Pump Arm Assembly

The 50cc Pump Arm Assembly from Quick Fuel Technology is an essential fuel system component designed for carburetor-equipped engines requiring precision mechanical fuel delivery. This compact assembly serves as the actuating linkage between your engine's throttle cable and the fuel pump mechanism, translating driver input into consistent fuel pressure and flow. Whether you're running a street engine, vintage restoration, or carbureted performance build, a properly functioning pump arm assembly is critical to reliable cold starts, smooth acceleration, and stable idle quality.

Quick Fuel Technology engineered this 50cc pump arm assembly with tight tolerances and durable construction to handle the repetitive mechanical cycling demands of daily driving or racing environments. The compact dimensions—measuring just 2.95 x 1.15 x 4.05 inches and weighing only 0.12 pounds—allow seamless integration into tight engine bay layouts without compromising performance or durability. The assembly's mechanical linkage operates independently of electrical systems, ensuring fuel delivery even in adverse conditions, making it ideal for vintage carburetors, mechanical fuel pumps, and traditional hot rod applications where reliability and simplicity matter most.

Mechanics and engine builders benefit from this assembly when restoring classic vehicles, upgrading carbureted engines, or replacing worn fuel system linkage that causes hesitation or stalling. Installation is straightforward for anyone with basic carburetor experience—the lightweight design reduces stress on mounting brackets while the proven Quick Fuel Technology engineering ensures years of hassle-free operation. If your vehicle exhibits rough idle, fuel starvation during acceleration, or exhibits worn pump linkage play, the 50cc Pump Arm Assembly (SKU QFT63-4) delivers the precision fuel system response your engine deserves.
