Description
Overview:
This Genuine Makita primer pump (MPN 168398-2) restores reliable fuel priming on compatible Makita petrol tools. It is a small hand-operated pump that moves fuel from the tank to the carburettor, clearing air from the lines to help the engine start more easily. The assembly typically uses a fuel‐resistant elastomer bulb with a robust plastic body for durability in everyday use. It is a straightforward replacement for worn, cracked or leaking pumps on machines such as the DCS230T chainsaw and EH5000W hedge trimmer. Suitable across selected Makita chainsaws, trimmers/brushcutters, blowers and cut-off saws, this part helps maintain consistent starting and smooth running after storage, routine servicing, or fuel line replacement. Being a Genuine Makita part ensures the correct fit and compatibility with the listed models.
