2002 Daewoo Lanos fueling problem

My gas gauge shows about 1/4 tank and I have no doubt the gauge is correct. The problem is when I try add fuel the tank will not accept fuel. It is like there is a bubble of sorts in the tank, it also pushes fuel out of the tank neck when attempting to fuel. I just attempted to refuel and it would only take one gallon before not accepting more, it appered in the neck to be full, but I know it is not. What can I do to correct this?
