Abstract: A vehicle refueling system provides for fuel delivery to, and refueling of, vehicles at their location when their fuel level falls below threshold values or based upon a scheduled delivery. A fuel level sensor, and one or more location sensors (e.g. GPS), are coupled via a computer system and wireless antenna to provide fuel level and position information to a fuel delivery system via a wireless communication network and to trigger fuel delivery and vehicle refueling at the vehicle's location. A vehicle processor system (VPS), and which may include an external computing resource ‘plug-in’ to an on-board diagnostic (OBD) port, performs or wirelessly communicates information associated with at least one of fuel level sensing, location determination, and electronic fuel door unlocking and/or alarm deactivation, such that the vehicle may be refueled at its location without requiring physical presence at the location by the user (e.g. vehicle owner).
