Description
4237 350 1400 STIHL Connector – Genuine OEM Fuel Tank Part
The STIHL Connector (4237 350 1400) is a genuine OEM fuel system component designed for use within the handle frame and fuel tank assembly of select STIHL professional hedge trimmers. This connector plays an important role in the fuel delivery or routing system, ensuring secure connections between fuel lines or tank-mounted components for reliable engine operation.
Over time, connectors may become brittle, cracked, or worn due to fuel exposure, vibration, heat, and aging. A damaged connector can lead to fuel leaks, air intrusion into the fuel system, hard starting, or inconsistent engine performance. Replacing it with the correct OEM part helps restore proper fuel system integrity without replacing the entire fuel tank assembly.
Manufactured to STIHL factory specifications, this genuine connector ensures correct fitment, secure sealing, and long-term durability under demanding operating conditions.
