The Honda 17620-Z4H-920 Fuel Filler Cap is a genuine OEM replacement designed for a wide range of Honda engines, tillers, two-stage snow blowers, and water pumps — including GX120, GX160, GX200, GX240, GX270, GX340, and GX390 horizontal shaft engines; FC600 and FRC800 tillers; HS724, HS928, HS1332, HS1336, HSM1336, HSS724, HSS928, and HSS1332 two-stage snow blowers; and WB20, WB30, WH15, WH20, WMP20, WT20, WT30, and WT40 water pumps. As a genuine Honda part, it is manufactured to the same standard as the cap that shipped with your equipment, ensuring a proper seal and correct venting for the fuel system. Because Honda supersedes parts across serial breaks, confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this fuel filler cap meets the same fit and sealing specification as the original, with no guesswork about compatibility.
- Fuel System Sealing — a correctly functioning cap maintains the closed fuel system, preventing fuel spillage, contamination, and vapor escape during operation and transport.
- Broad Honda Fitment — covers GX-series horizontal shaft engines, FC600 and FRC800 tillers, HS and HSS two-stage snow blowers, and multiple Honda water pump models, including the WB, WH, WMP, and WT lines.
- Check Your Serial Number — Honda updates part numbers at production serial breaks; verify your machine's serial number against the fitment table to confirm part number 17620-Z4H-920 is correct for your unit.
The fuel filler cap seals the opening of the fuel tank, keeping the fuel supply clean and contained while allowing controlled pressure equalization between the tank and the atmosphere. A vented cap prevents vacuum lock and pressure buildup that would otherwise interrupt fuel delivery and cause the engine — or engine-powered equipment — to run poorly or stall. When the cap seal deteriorates or the cap is lost, fuel can leak or become contaminated, creating both a performance problem and a hazard; replacing it promptly with the correct OEM cap restores a properly sealed and vented system.
