Description
Overview:
This Fuel Hose Purge is a genuine Husqvarna replacement part for pro-grade chainsaws such as the 550 XP Mark II and 550 XP G Mark II. It manages the purge/primer return path to keep fuel circulating correctly between the carburettor and tank, helping your saw start reliably and run smoothly. Built from fuel‐resistant elastomer and durable polymer components, it withstands petrol, oil, vibration and heat in daily use. Supplied to Husqvarna specification under MPN 525344303 (OEM No. 525 34 43 03), it is designed for a precise fit on listed models. Replacing a worn or cracked purge hose helps prevent air leaks and fuel seepage, maintaining performance, reducing downtime, and supporting both professional and domestic maintenance routines.
