The Honda 17703-Z0H-821 Fuel Tube A is a genuine OEM replacement designed for FG110 tillers and GX25 horizontal shaft engines. As a direct Honda OEM component, this fuel tube is manufactured to match the original routing, diameter, and connection points of the factory part. This part is a straightforward service item — if you're chasing a fuel delivery problem or replacing aging rubber, confirming part number 17703-Z0H-821 against your machine's serial number in the fitment table is the right first step, as Honda updates parts at production breaks.
Key Features
- Genuine OEM Fuel Delivery — manufactured by Honda to the same specifications as the original, ensuring consistent fuel flow from the tank to the carburetor without restriction or seepage at the connection points.
- Direct Replacement Fit — engineered to match the original tube geometry and end fittings, so installation on FG110 tillers and GX25 engines requires no trimming or adaptation.
- Broad Compact-Engine Coverage — fits the FG110 tiller and GX25 horizontal shaft engine, making it a useful stocking item for anyone who services Honda's small-displacement mini 4-stroke equipment.
- Serial Number Verification Recommended — Honda supersedes fuel system components at production breaks, so confirm your machine's serial number against the fitment table before ordering to ensure this is the correct tube for your unit.
The Fuel Tube A carries gasoline from the fuel tank to the carburetor, maintaining a sealed, unobstructed path so the engine receives a steady, correctly metered supply of fuel. Over time, small-diameter fuel tubes can harden, crack, or develop pinhole leaks that starve the carburetor or allow fuel to weep onto hot engine surfaces. Replacing a degraded tube restores consistent fuel delivery and keeps the engine starting cleanly and running at the power level the operator expects.
