Description
Overview:
This Tank Vent is a Genuine Stihl part for preventing pressure build‐up in small petrol tool fuel tanks. It maintains steady airflow so the tank can breathe, helping fuel to flow consistently and the engine to run reliably. Built from durable, fuel‐resistant plastic with an internal one‐way valve, it is designed for long‐reach hedge cutters and other handheld Stihl machines where a compact, dependable vent is required. It is commonly fitted to models such as the Stihl HL91K and HL92C. The manufacturer part number is 4149 350 5800. Replacing a blocked or leaking vent restores proper tank ventilation, reduces the risk of vacuum‐related stalling, and supports smooth starting and idling during everyday trimming and maintenance work.
