Description
Overview:
This Tank Vent is a genuine Stihl component designed for mid-size Stihl chainsaws, including the 024 and 034. Built from fuel‐resistant polymer, it allows air into the fuel tank while helping to prevent vacuum build‐up that can cause fuel starvation and erratic running. By maintaining steady tank pressure, it supports consistent fuel flow for smooth cutting performance across the rev range. As an OEM Stihl part (1121 350 5800), it provides the correct fit and function for the specified platforms. The compact, push‐fit design makes replacement straightforward during routine servicing or when resolving symptoms such as surging, stalling, or loss of power as the tank level drops. Genuine Stihl quality ensures reliable sealing and long service life in demanding forestry and garden use.
