The KAWASAKI 99996-6101 is a cap tank and breather kit designed as an OEM replacement component for Kawasaki small engine applications. This kit includes the fuel or oil tank cap along with the breather assembly, which together maintain proper venting and sealing for the engine fuel or oil system. A correctly functioning tank cap and breather prevent pressure buildup, fuel spillage, and contaminated air intake caused by a failed or worn cap seal or breather element. This kit is typically installed by small engine technicians and outdoor power equipment service professionals during routine maintenance or component failure diagnosis.
This kit applies to Kawasaki-powered lawn and garden equipment. Common install scenarios include replacing a cracked or non-sealing tank cap, a clogged or damaged breather, or both during a single service call. Using the OEM Kawasaki kit ensures the cap thread pitch, seal dimensions, and breather flow rate match the original factory specifications for the target engine.
Designed as an OEM-style replacement kit for Kawasaki small engines used in lawn and garden equipment. Refer to your engine model and serial number against the Kawasaki parts catalog to confirm fitment before installation.
Installation is typically performed by a small engine technician or qualified outdoor power equipment service professional. Before servicing, shut off the engine, allow it to cool completely, and work in a well-ventilated area away from ignition sources when handling fuel system components. Inspect the tank filler neck threads and sealing surface before installing the new cap to ensure no damage is present. Dispose of old fuel-contaminated components in accordance with local regulations.
