Won't take gas

We have a 2000 Concorde LXi and it takes forever to put gas in. Is there a vent that could be plugged. This is terribly frustrating.

sounds like maybe you got some gunk inside the fuel neck blocking the flow, to remedy this, you would need to drop the tank and take the fuel neck off and see if something is clogged in there. not an easy job, seeing how the tank can weigh more than 100lbs
