Description
Overview:
This Fuel Tank Vent is a genuine Husqvarna part designed to keep your machine running reliably by maintaining correct air flow into the fuel tank. Built from fuel‐resistant polymer with an internal one‐way valve, it helps prevent vacuum build‐up that can restrict fuel delivery and cause stalling or loss of power. It is engineered for Husqvarna professional and domestic machines, including the 371K cut-off saw and 262XP chainsaw, for a precise fit and dependable sealing. The vent replaces OEM No. 501 87 31-01 and matches the original specification for performance and durability. Suitable for use in demanding, dusty environments, it offers a straightforward replacement when the original breather is blocked, damaged, or allowing fuel leakage. Genuine Husqvarna quality ensures long service life and consistent operation.
