The Honda 17511-Z6K-821 Fuel Tank is a genuine OEM replacement designed for GX35 and GX50 horizontal shaft engines and HHT35 and UMC435 trimmers. As a direct Honda OEM component, this fuel tank is manufactured to the same specifications as the original part it replaces, ensuring a proper fit without modification. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this tank may not apply to every production run of each model.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this tank meets the same dimensional and capacity requirements as the original, so fuel delivery to the engine remains consistent and uninterrupted.
- Broad Model Coverage — fits GX35 and GX50 horizontal shaft engines as well as HHT35 and UMC435 trimmers; confirm your model and serial number against the fitment table to identify the correct application.
- Direct OEM Replacement — mounts in place of the factory tank with no rework required, restoring the fuel system to its original configuration.
- Serial Number Verification Recommended — Honda updates part numbers across production breaks, so check your unit's serial number against the compatibility table to confirm this is the right tank for your machine.
The fuel tank stores the gasoline supply that feeds the carburetor, keeping the engine running through the full duration of a job. A cracked, leaking, or deteriorated tank starves the engine of fuel, causes hard-starting, and creates a fire hazard — making prompt replacement essential. On compact engines like the GX35 and GX50, and on handheld tools like the HHT35 and UMC435 trimmers, the tank is sized and shaped specifically for the unit, so an exact-fit OEM replacement is the most straightforward way to restore normal operation.
