The Honda 16852-Z6H-003 Fuel Tube B (FKM) is a genuine OEM replacement designed for GXV670 vertical shaft engines. As a direct Honda OEM component, this fuel tube is manufactured to the same specifications as the original part installed at the factory, ensuring a correct fit within the fuel delivery system. Honda supersedes parts at serial number breaks, so verify your engine's serial number against the fitment table before ordering to confirm part number 16852-Z6H-003 is correct for your unit.
Key Features
- FKM Construction — the FKM (fluoroelastomer) compound in this fuel tube offers superior resistance to fuel degradation, making it the correct specification for the GXV670 fuel system where a standard rubber tube would deteriorate prematurely.
- Genuine OEM Honda Part — sourced directly from Honda, this tube matches the original routing, diameter, and end-fitting geometry of the part it replaces, supporting a straightforward, accurate installation.
- GXV670 Fitment — designed specifically for GXV670 vertical shaft engines; confirm your serial number against the fitment table to ensure this is the correct variant for your engine's production range.
- Fuel Flow Integrity — a cracked, swollen, or hardened fuel tube restricts or leaks fuel, causing rough running, hard starting, or fuel seepage; replacing a degraded tube restores clean, uninterrupted fuel delivery.
A fuel tube carries gasoline from one point in the engine's fuel delivery circuit to another — typically between the fuel valve, fuel filter, or carburetor — maintaining a sealed, unobstructed path for the fuel supply. When the tube degrades, it can collapse internally to restrict flow, crack to cause an external fuel leak, or swell at its ends to lose a secure seal. On a GXV670 vertical shaft engine, keeping this connection intact is essential to consistent fuel metering and reliable starts; an FKM-compound tube holds its shape and flexibility over a longer service life than a standard rubber equivalent, particularly in environments where fuel blends and heat cycles accelerate ordinary rubber wear.
