Description
Overview:
This Grommet Assembly is a Genuine Honda OEM fuel tank sealing unit for Honda small engines and brushcutters, including the GX35 and HHT35S. Supplied under OEM No. 17700-Z0Z-307, it replaces the original tank bung to restore a secure, leak-free connection where the fuel lines pass through the tank. The assembly uses a tough, fuel-resistant black rubber grommet and is typically supplied with pre-fitted fuel lines and an in-tank fuel filter for consistent fuel delivery. By renewing the tank seal and line interface, it helps prevent petrol leaks and vapour escape, supports reliable starting, and maintains correct engine performance. It is designed for straightforward replacement during routine maintenance or when the original grommet has hardened, cracked, or swollen.
