The Honda 16851-Z6H-023 Fuel Tube (FKM) is a genuine OEM replacement designed for the GXV670 vertical shaft engine. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a proper connection within the fuel delivery system. This fuel tube is the correct choice for GXV670 engines, so confirm your engine's serial number against the fitment table before ordering to ensure you have the right part for your production run.
Key Features
- FKM Construction — the FKM (fluoroelastomer) designation identifies this as a fuel-resistant tube grade suited to the demands of continuous fuel exposure in the GXV670 engine's fuel circuit.
- Genuine Honda OEM Part — sourced directly from Honda, part number 16851-Z6H-023 is the same component installed at the factory, eliminating guesswork on material grade or dimensional compatibility.
- GXV670 Fitment — built specifically for the GXV670 vertical shaft engine; verify your serial number against the fitment table, as Honda supersedes parts at serial breaks.
- Fuel Flow Integrity — a cracked, hardened, or deteriorated fuel tube restricts or leaks fuel, leading to hard starting, rough running, or fuel delivery failure; this genuine replacement restores consistent flow to the carburetor.
The fuel tube carries gasoline from the tank or fuel valve to the carburetor, maintaining a sealed, unobstructed path so the engine receives a steady supply of fuel. Over time, fuel tubes can harden, crack, or swell depending on the fuel blend they are exposed to — symptoms that show up as fuel leaks, fuel starvation, or erratic engine behavior. The FKM material designation on this tube indicates a fluoroelastomer compound selected for its resistance to fuel degradation, making it the appropriate replacement when the original tube shows signs of deterioration on a GXV670 engine.
