In a fuel port forming portion that forms a fuel port, a portion of a peripheral wall located on a perpendicular lower side when a fuel supply device is in a mounting posture of being mounted to a vehicle formed as a convex drain groove from a corner portion at which an insertion-side open/close member for opening/closing the fuel port makes contact with an open base portion of the fuel port to an open end side of the fuel port. The drain groove is inclined in a horizontal direction such that the open end side of the fuel port is located closer to the perpendicular lower side than a corner portion side when the fuel supply device is in the mounting posture, to thereby improve draining function of the drain groove provided to the fuel port.

In a housing surrounding a nozzle insertion passage, a first opening open to the atmosphere is provided, and in a cover main body in which the housing is incorporated, a nozzle insertion port and a second opening which is opposite the first opening and open to the atmosphere is provided. Moreover, in the recess wall of a drainage port formation member fitted to the first opening, a recess which is recessed on the side of the first opening is formed so as to be continuous with the second opening, and a drainage port is provided. A drainage valve is held in the recess with respect to the recess wall so as to open and close the drainage port by turning of the valve main body about the turning shaft serving as a base point.

A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.

A capless closure device including a body, an end plate provided with a circular opening adapted for receiving a fuel nozzle, and a flap door adapted to close the circular opening, where the capless closure device includes a latch edge arranged at the lower edge of the circular opening and a spaced apart sealing edge, and where an inlet drain opening is arranged between the latch edge and the sealing edge. The advantage of the invention is that a capless closure device with an integrated drain passage is provided in a cost-effective way.

Methods and systems are provided for nozzle guides for vehicle refueling adapters. In one example, a nozzle guide includes a plurality of protrusions adapted to center a fuel nozzle within the nozzle guide and to reduce a likelihood of over-insertion of the fuel nozzle into the nozzle guide. The nozzle guide may include features such as a rear guard and upper wall adapted to reduce ingression of liquid fuel with fuel vapor flowing from the fuel tank.

The invention relates to a filler pipe (1) weldable to a liquid tank (3) of a vehicle, wherein the filler pipe comprises a main body (4), a secondary body (5) configured to support an inlet check valve (2) and a weldable flange (6) suitable for welding around an opening in the liquid tank (3), the weldable flange (6) extending between the main body (4) and the secondary body (5).

An automatic opening and closing device for a fuel inlet of a vehicle may include a cap cover mounted at the fuel inlet of the vehicle, a fuel cap pivotably mounted at the cap cover and configured to selectively open or close the fuel inlet by being pivoted inside the fuel inlet, and a fuel cap operating mechanism mounted in the fuel inlet and configured, when the fuel door is closed, to pivot the fuel cap by being pressed by the fuel door to close the fuel inlet, and, when the fuel door is opened, pivot the fuel cap to open the fuel inlet according to release of pressing by the fuel door.
