The Honda 91424-ZBC-812 Fuel Tube (4.2X120) is a genuine OEM replacement designed for GX270 and GX390 horizontal shaft engines. As a direct Honda OEM component, this fuel tube is manufactured to the exact dimensions and material properties specified for these engines, ensuring a proper seal and consistent fuel flow from tank to carburetor. Sourced directly from Honda, this part carries the same part number 91424-ZBC-812 used by Honda dealers and service technicians worldwide.
Key Features
- Correct Dimensions for Consistent Fuel Delivery — at 4.2 mm inner diameter and 120 mm length, this tube matches the original routing path and connection points on GX270 and GX390 engines, maintaining the steady fuel flow the carburetor depends on
- Genuine OEM Part — manufactured by Honda to original specifications, so the fit and fuel compatibility match what came off the assembly line — no trimming, adapting, or improvising required
- Covers GX270 and GX390 Horizontal Shaft Engines — listed for both engine models; Honda does supersede parts at serial-number breaks, so confirm part number 91424-ZBC-812 against your engine's serial number before ordering
- Restores Fuel System Integrity — a cracked, hardened, or kinked fuel tube restricts flow and causes lean running, hard starting, or fuel leaks; replacing it with this OEM tube brings the fuel system back to proper working order
The fuel tube carries gasoline from the fuel tank to the carburetor, forming a critical link in the engine's fuel delivery system. It must maintain a flexible, leak-free seal at both ends while resisting the softening and cracking that fuel exposure and heat cause over time. When the tube deteriorates — whether from age, fuel degradation, or heat cycling — the engine may run erratically, fail to start, or develop a fuel leak; replacing it promptly with the correct OEM part restores safe, reliable fuel delivery.
