A capless refueling assembly for opening and closing a filler neck of a gas tank. The refueling assembly includes a housing attached to the filler neck. A lid is pivotally mounted to the housing between open and closed positions for facilitating the opening and closing of the filler neck. A valve mechanism is movably mounted to the housing between seated and unseated positions for selectively releasing pressurized fluid from the filler neck. The refueling assembly is characterized by an actuation device automatically moving the valve mechanism from the seated position to the unseated position while the lid remains in the closed position. Accordingly, any pressurized fluid within the filler neck is vented to a safe area, preferably a carbon canister, before the lid is moved to the open position.
