The Honda 17701-Z3V-803 Fuel Tube (FKM) is a genuine OEM replacement designed for GX50 horizontal shaft engines. As a direct Honda OEM part, this fuel tube is manufactured to the same specifications as the original component it replaces, ensuring a proper fit without modification. This part is built for GX50 engines, so confirm your engine's serial number against the fitment table before ordering to make sure part number 17701-Z3V-803 is the correct match for your serial range.
Key Features
- FKM Construction — the FKM (fluoroelastomer) designation means this tube is engineered to resist fuel degradation, maintaining a secure, leak-free fuel pathway over extended service life in GX50 engines.
- Genuine Honda OEM Part — sourced directly from Honda, this fuel tube matches the original dimensions and connection geometry, so it seats correctly without any trimming or adaptation.
- GX50 Engine Fitment — built specifically for the GX50 horizontal shaft engine; verify your serial number against the fitment table, as Honda supersedes parts at serial breaks.
- Fuel System Integrity — a cracked, hardened, or deteriorated fuel tube causes fuel starvation, rough running, or fuel leaks; replacing it with this OEM tube restores consistent fuel delivery to the carburettor.
The fuel tube carries gasoline from the fuel tank to the carburettor, maintaining a steady, unobstructed flow that the engine depends on for consistent starting and smooth operation. On small-displacement engines like the GX50, even a minor crack or pinhole in the tube can introduce air into the fuel line, causing lean-running conditions, hard starting, or stalling under load. Replacing a degraded tube with a fresh OEM part restores the sealed fuel pathway the carburettor needs to meter fuel accurately.
