What VA DUC said! If a line comes off inside the tank, or if there is a hole in one of those lines, you could get fuel out the overflow. Use a flashlight to look inside the tank for an unattached line. Also, check the black rubber vent at the cap to make sure it seats properly and is not blocked. With 1/2 tank of fuel and 2-3 ounces coming out something is up.
