Shindaiwa p004002520 Primer Pump Assembly

Product Description

The SHINDAIWA p004002520 is a primer pump assembly designed to deliver fuel to the carburetor during cold starts on small gasoline-powered outdoor power equipment. The primer pump draws a measured charge of fuel into the carburetor throat, reducing the number of pulls required to start the engine. This part is a direct replacement assembly, meaning it includes the bulb and body components needed for a complete swap. It is typically serviced by small-engine technicians, landscaping equipment mechanics, and experienced DIYers performing carburetor or fuel system maintenance.

This primer pump assembly is used in handheld outdoor power equipment where a manual primer bulb is integrated into the fuel delivery system. Typical applications include string trimmers, brush cutters, and similar SHINDAIWA-branded handheld units that rely on a priming step before startup. It is suited for both routine maintenance intervals and failure-driven replacement when the original bulb cracks, hardens, or fails to draw fuel properly.

Installation Notes

Installation should be performed by a qualified small-engine technician or a trained equipment mechanic. Before beginning work, disconnect the spark plug wire to prevent accidental engine startup and relieve any residual fuel system pressure. Fuel system components should be handled in a well-ventilated area away from ignition sources, following applicable safety codes for flammable liquids. Inspect all connected fuel lines for cracking or wear and replace as needed before returning the equipment to service.
