The Honda 17631-899-010 Fuel Filler Cap Gasket is a genuine OEM replacement designed for Honda EB, EG, EM, and EU series generators, including the EB10000, EB3800, EB4000, EB5000, EB6500, EG4000, EM3800, EM4000, EM5000, EM6500, EU3000, and EU7000. As a direct Honda OEM part, this gasket is manufactured to the same specification as the original, ensuring a proper seal at the fuel filler cap. Confirm your generator's model and serial number against the fitment table before ordering, as Honda updates parts at production breaks.
Key Features
- OEM Fuel Sealing Integrity — Genuine Honda construction ensures the gasket seats correctly against the filler neck, forming the tight seal needed to prevent fuel vapor escape and keep contaminants out of the tank.
- Direct OEM Replacement — Sourced directly from Honda, part number 17631-899-010 installs in place of the original gasket with no modification required to the filler cap or tank neck.
- Broad Generator Compatibility — Fits a wide range of Honda conventional and inverter generators, including the EB, EG, EM, and EU series; verify your model in the fitment table to confirm applicability.
- Check Your Serial Number — Honda revises parts at defined production points; cross-reference your generator's serial number with the compatibility data to ensure this is the correct gasket for your unit.
The fuel filler cap gasket forms the sealing interface between the fuel cap and the opening of the fuel tank. It prevents fuel from leaking around the cap during operation and transport, and stops moisture, dust, and debris from entering the fuel supply. When this gasket hardens, cracks, or deforms with age, the seal breaks down — leading to fuel odor, seepage around the cap, and the risk of contamination entering the tank. Replacing a worn gasket with a genuine Honda part restores the original seal and keeps the generator's fuel system properly closed.
