The Honda 17631-Z1T-810 Fuel Filler Cap Gasket is a genuine OEM component designed for a wide range of Honda engines, water pumps, tillers, snow blowers, and inverter generators. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a proper seal at the fuel filler cap. This gasket is compatible with a broad range of Honda equipment, including GX120, GX160, GX200, GX270, GX340, and GX390 horizontal shaft engines, WT20, WT30, WT40, WB20, WB30, WH15, WH20, and WMP20 water pumps, FC600 and FRC800 tillers, HS724, HS928, HS1332, HS1336, HSM1336, HSS724, HSS928, and HSS1332 two-stage snow blowers, and EB2800 and EG2800 inverter generators. Because Honda supersedes parts at production breaks, confirm your machine's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Sealing — manufactured by Honda to the original specification, delivering the same cap-to-filler-neck seal as the part it replaces.
- Fuel-System Integrity — a sound filler cap gasket prevents fuel vapors from escaping and keeps moisture and debris out of the tank; a cracked or compressed gasket does neither.
- Broad Cross-Equipment Fitment — one part number covers GX-series horizontal shaft engines, multiple Honda water pump models, tillers, two-stage snow blowers, and EB2800 and EG2800 inverter generators; verify your model and serial number against the fitment table.
- Serial-Number Verification Recommended — Honda updates part numbers at production breaks, so always cross-reference your machine's serial number to confirm part number 17631-Z1T-810 is correct for your specific unit.
The fuel filler cap gasket forms the seal between the fuel cap and the filler neck of the fuel tank. Its job is to prevent fuel and fuel vapors from escaping when the cap is closed, while also blocking contaminants from entering the tank. When this gasket deteriorates, cracks, or loses its compression, the cap no longer seals correctly — the result can be fuel odor, slow evaporative loss, or the entry of dirt and water that can compromise fuel quality and damage the fuel system downstream.
