The Honda 91424-Z5F-812 Fuel Tube (4.5X190) is a genuine OEM component designed for GX240, GX340, and GX390 horizontal shaft engines. As a direct Honda OEM part, it meets the same specifications as the original tube installed at the factory, ensuring a proper fit within the fuel delivery system. Sourced directly through authorized Honda channels, this fuel tube is the correct replacement when the original shows cracking, hardening, or fuel seepage. Always confirm fitment against your engine's serial number using the compatibility table before ordering.
Key Features
- Correct Fuel Delivery Geometry — sized at 4.5 mm inner diameter and 190 mm length, matching the OEM routing and connection points in the GX240, GX340, and GX390 fuel circuit
- Genuine Honda OEM Part — manufactured to Honda's original specification, so it seals securely at both ends without the fitment compromises a non-OEM tube can introduce
- Covers Three GX-Series Engines — listed for GX240, GX340, and GX390 horizontal shaft engines; confirm your engine's serial number against the fitment table, as Honda supersedes parts at serial breaks
- Restores Fuel System Integrity — a cracked or hardened fuel tube causes fuel starvation, hard starting, or external fuel leaks; replacing it with part number 91424-Z5F-812 brings the delivery circuit back to proper working order
The fuel tube carries gasoline from the tank or fuel valve to the carburetor inlet, maintaining a steady, leak-free supply under the vibration and heat conditions normal to engine operation. Over time, the rubber or composite material can harden, crack, or soften, causing fuel flow restrictions or external leaks that starve the carburetor and prevent the engine from starting or running cleanly. Replacing a deteriorated tube promptly keeps fuel reaching the carburetor at the correct rate and eliminates the fire and performance risk that a leaking line presents.
