The Honda 17620-Z28-000 Fuel Tank Cap Assembly is a genuine OEM component designed for the EU3000 inverter generator. Sourced directly from Honda, this cap assembly carries the exact fit, thread pattern, and sealing performance of the original part it replaces. If your existing cap is cracked, stripped, or no longer sealing correctly, this is the correct Honda replacement to restore proper fuel system integrity.
Key Features
- OEM Sealing Performance — engineered to Honda's original specification, this cap assembly forms a tight, secure seal against the fuel tank filler neck, preventing fuel vapor escape and keeping contaminants out of the tank
- Direct OEM Replacement — an exact fit for the EU3000 inverter generator; installs directly in place of the original cap with no modifications to the tank neck or surrounding hardware
- Serial Number Verification Recommended — Honda updates parts at production breaks, so confirm your EU3000 serial number against the fitment table before ordering to ensure part number 17620-Z28-000 is correct for your unit
- Protects Fuel System Integrity — a failed or improperly seating cap can allow moisture ingress and fuel evaporation, both of which affect generator run quality and fuel efficiency over time
The fuel tank cap assembly seals the filler opening on the EU3000's fuel tank, keeping fuel securely contained during operation, transport, and storage. A properly functioning cap maintains the correct venting balance for the fuel system — when it wears out, cracks, or loses its sealing surface, fuel odors, seepage, and potential contamination become real concerns. Replacing a damaged cap with a genuine Honda part restores the original seal and ensures the generator's fuel system operates as intended.
