The Tank Vent Assembly (New Type) for Stihl TS400 is a genuine Stihl OEM component that controls airflow into the fuel tank to prevent vacuum build-up and fuel starvation. Built from fuel‐resistant plastics with a robust one‐way valve design, it maintains stable tank pressure and consistent fuel delivery.
