Description
Overview:
This Diaphragm Pump is a Genuine Honda part for small four‐stroke engines, including the GX22 and GX25 ranges, and also suits GX31 and GX35 variants. It sits within the carburettor assembly to help draw and meter fuel, keeping an air‐tight seal so the engine starts cleanly and runs steadily. Built from durable, fuel‐resistant diaphragm materials, it is designed for long service in handheld and portable equipment. The precise moulding and port layout match Honda specifications for an accurate, leak‐free fit. Ideal for brushcutters, hedge trimmers and multi‐tools that use these engines, it restores proper priming and fuel delivery without modification. Part number 16014‐ZM3‐004 supports reliable everyday use in garden and light construction tools where consistent performance and easy maintenance are essential.
