Abstract
Methods and systems are provided for enabling a vehicle operator to select a desired amount of fuel to add to a fuel tank, and wherein overfilling of the tank is prevented by pressurizing the fuel system with an onboard pump. In one example, the tank may be sealed to induce an automatic shutoff of a refueling dispenser if the fuel level is below the capacity of the tank, and in another example, wherein it is indicated that the tank is full, the fuel system may be pressurized via the pump to induce automatic shutoff of the refueling dispenser and to prevent further overfilling of the tank. In this way, vehicle operators may add desired amounts of fuel to the tank wherein shutoff of the refueling dispenser is automatic, and wherein liquid fuel entering an evaporative emissions control system as a result of overfilling a fuel tank is prevented.
