A capless refueling port attached to a fuel tank of a vehicle is presented. In one example, the capless refueling port includes a main opening, an articulating unitary plug mounted within a nozzle chamber of the fuel port, and a drain tube. The articulating plug is configured to partially or fully close an inlet of the drain tube connected to the fuel port during refueling; the articulating plug is further adjusted to open after refueling, allowing the fuel port to dissipate any residual pressure in the nozzle chamber to the atmosphere.
