Do you know whether you were able to remove the piece of debris from the line or from the fuel tank? If not, the problem might recur. A flashlight that can focus to a tight beam and a siphon pump, e.g., <

Another possibility is to run the tank dry, and then to use a vacuum cleaner or a compressed-air line to suck or to blow the crud out of the tank. If using an electrically powered vacuum cleaner, first consider the issue of sparks from the electric motor and fuel vapor. A vacuum cleaner with a brushless electric motor will be a safer bet. Proceed at your own risk.
Consider also the matter of fuel-pump priming. My dealer's advice when I bought my 4500Y was to never let the fuel level drop too low because repriming the fuel-delivery system is a pain. This might not be an issue, or as much of an issue, in your gasoline-powered 4500Z.
