Why is gas leaking in truck of my 1990 Lincoln town car

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A gas leak in the trunk of your 1990 Lincoln Town Car is definitely a cause for concern! This issue could stem from a few different sources. Common culprits include a damaged fuel filler neck, a loose or cracked fuel tank, or a failing gasket or seal in the fuel system. It's also possible that the fuel lines running to or from the tank might be corroded or damaged. Since you mentioned it leaks both while driving and parked, it’s critical to address this issue promptly, as it poses a serious fire hazard. I recommend getting it checked out by a professional before you take it on the road again.
