Abstract
This disclosure is directed to vehicle fuel systems capable of isolating the energy within a fuel tank from the vehicle user. An exemplary fuel system may include a first valve located within a fuel inlet conduit and a second valve located within a vapor recovery recirculation line of the fuel system. The first and second valves may be controlled based on the pressure inside a fuel tank of the fuel system. Fuel may only be transferred into the fuel tank when the fuel tank is within a predefined threshold pressure range. A depressurization sequence of the fuel tank may be automatically initiated when a fuel door of the fuel system is moved to an open position. The positioning of the fuel door may be monitored by a fuel door position monitoring device.
