The Honda 17620-Z22-010 Fuel Filler Cap is a genuine OEM replacement designed for Honda EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, EM6500, and EP2500 generators. As a direct OEM component, it is manufactured to the same specification as the original part that left the factory, ensuring a proper seal on the fuel tank. Because Honda supersedes parts across serial number breaks, confirm your generator's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Seal Integrity — manufactured to Honda's original specification, this cap seats and seals the fuel tank opening exactly as the factory part did, preventing fuel vapor loss and contamination
- Direct-Fit Replacement — designed as a drop-in replacement for part number 17620-Z22-010, this cap installs without modification on compatible Honda generators
- Broad Generator Compatibility — covers a wide range of Honda conventional generators, including the EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, EM6500, and EP2500
- Serial Number Verification Recommended — Honda revises parts at production breaks, so check your unit's serial number against the fitment table to confirm this is the correct cap for your generator
The fuel filler cap seals the opening at the top of the generator's fuel tank, keeping the fuel supply free from dirt, debris, and moisture while allowing the tank to vent properly during operation. A cap that no longer seats correctly can allow contaminants into the fuel system or permit fuel vapors to escape, both of which affect generator performance and safe operation. Replacing a worn or damaged cap with the correct OEM part restores a proper seal and keeps the fuel system functioning as intended.
