Q: Why does gas back up when filling tank and pump keeps cutting off. on 2004 Lincoln Town Car

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
can't fill up gas tank, gas backs up and pump cuts off
It could be the vent line is broken/bent or not connected or clogged. If you remove the fuel tank and replace the filler neck (it should come with a vent line) you will be good to go. I would also check the tank for any issues such as rust or dirt that can clog things.
