The Honda 16950-ZA0-804 Petcock Assembly is a genuine OEM component designed for the EX5500 generator. Sourced directly through Honda's parts program, this assembly is an exact match for the original unit, ensuring proper fuel shutoff function and a drop-in fit with no guesswork. Buyers should confirm the part number 16950-ZA0-804 against their unit's serial number using the fitment table to ensure compatibility with their specific production run.
Key Features
- Genuine OEM Fuel Control — manufactured to Honda's original specifications, delivering the correct flow rate and shutoff action the EX5500 generator demands
- Direct OEM Replacement — designed as a direct replacement for the original petcock on the EX5500, so installation aligns with existing fuel line connections without adaptation
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so cross-check your generator's serial number against the fitment table before ordering
- Fuel System Integrity — a functioning petcock keeps fuel delivery controlled and predictable; a leaking or stuck valve can starve the engine of fuel or cause an uncontrolled flow when the generator is not in use
The petcock assembly is the manual fuel shutoff valve mounted between the fuel tank and the carburetor. It controls whether fuel flows to the engine, allowing the operator to cut the fuel supply when storing the generator or performing service. When the petcock fails — whether through a stuck valve, a cracked body, or a deteriorated seal — fuel can leak or fail to reach the carburetor entirely, leaving the generator unable to start or run. Replacing a worn petcock restores proper fuel management and prevents fuel-related hazards during storage.
