The Honda 17703-Z8B-803 Fuel Tube B (FKM) is a genuine OEM fuel line component designed for GCV160 vertical shaft engines. As a direct Honda OEM part, this fuel tube is manufactured to the same specification as the original, ensuring a correct, trouble-free installation. Honda supersedes parts at serial breaks, so confirm your engine's serial number against the fitment table before ordering to be sure this is the right tube for your unit.
Key Features
- FKM Construction — the FKM designation identifies a fluoroelastomer compound, a material well-suited to sustained contact with fuel; this is the grade Honda specifies for this tube on the GCV160
- Genuine Honda OEM — sourced directly from Honda, this tube carries part number 17703-Z8B-803 and matches the original routed length and end dimensions exactly
- GCV160 Fitment — built specifically for GCV160 vertical shaft engines; confirm your serial number against the fitment table to ensure this is the correct supersession for your engine
- Fuel Delivery Integrity — a cracked or hardened fuel tube causes fuel starvation, erratic running, or fuel weeping at the connection points; replacing it with the correct OEM tube restores a clean, uninterrupted fuel supply
The fuel tube carries gasoline from the tank to the carburetor, maintaining a steady, sealed flow that the engine depends on for consistent starting and smooth operation. Over time, fuel line rubber degrades — it hardens, cracks, or softens from prolonged fuel exposure — and a compromised tube will starve the carburetor or allow raw fuel to seep at its fittings. Replacing a worn fuel tube with the correct Honda OEM part restores a leak-free fuel path and brings the engine back to reliable, even running.
