美国采购需求：鼓风机

I recently purchased a product from Amazon, but I've encountered an issue that needs resolution. The unit has a problem with the fuel pipe insert on top of the fuel tank, which is causing it to leak fuel. This is obviously a safety concern and affects the overall performance of the product. I'm looking to obtain a replacement insert to resolve this issue as soon as possible. It's crucial for me to get the unit functioning properly again to avoid any further complications. If you have the replacement part available, please let me know the pricing and availability. I appreciate your assistance in helping me get this sorted out promptly. Thank you!
