#### **Cons:**1. **Cost** OEM parts are more expensive than aftermarket alternatives (typically **$50 $100** for the hose alone, plus labor if professionally installed).
2. **Installation Complexity** The fuel filler neck is located near the fuel tank, and removal may require draining some fuel, disconnecting electrical connectors, and possibly removing the rear seat or trunk liner for better access.
