Description
Overview:
The tank vent (OEM No. 4147 350 5802) is a genuine Stihl fuel tank breather for petrol-powered handheld machines. It is a small, durable plastic valve that allows the fuel tank to breathe, preventing vacuum or pressure build-up that can restrict fuel flow or cause erratic running. Designed for Stihl tools such as the HL91K and HL92C hedge trimmers, it is also used across selected brushcutters, clearing saws and Kombi engines. Fitting a working vent helps maintain consistent engine performance, smooth idling and reliable restarts during long trimming or brushcutting sessions. This genuine part matches original factory specification for fit and function, making it a straightforward, like-for-like replacement when your existing vent becomes blocked, damaged or fuel-soaked.
Key Features:
- Genuine Stihl part for correct fit and performance (OEM ref. 4147 350 5802)
