Is it possible for a fuel line to be corroded under 14k

Hello, perhaps obtain a second opinion from another repair shop? Or another dealership? It's not very likely for corrosion to be present if no corrosion source is near, but I can't observe your vehicle so I cannot say for sure. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
