Description
Overview:
This Genuine Stihl tank vent (MPN 1117 350 5800) is a small, fuel‐system breather used on Stihl petrol chainsaws, including the 028 and 048. It is built from durable, fuel‐resistant materials and contains a vent insert to admit air into the tank while the engine runs. By preventing vacuum build‐up, it keeps fuel flowing to the carburettor so the saw idles, accelerates, and cuts reliably. The compact assembly is engineered for an accurate fit on specified models and integrates cleanly with the existing fuel system. Suitable for both professional and domestic users, this vent helps maintain consistent performance during felling, cross‐cutting, and general maintenance tasks where dependable fuelling is essential.

- Genuine Stihl part for assured compatibility and fit on listed models
- Maintains correct tank breather function to prevent vacuum lock and fuel starvation
