A fuel delivery system automatically selects one out of several available fuels for a vehicle having a specialized fuel filler neck. A dispenser pump assembly includes a pump base, a hose assembly and a nozzle assembly which includes a nozzle spout and a cylindrical collar member slidably mounted on the nozzle spout. A sensor on the nozzle assembly generates a signal, based on a position of the collar when the spout is fully inserted into a fuel filler neck of the vehicle. The signal is transmitted via wires, wireless signal, fiber-optic cables or other medium. An electronic controller in the pump base selects an appropriate fuel, based on the signal received from the sensor. If the available fuels include percentages of ethanol or other additives, a precision blending system ensures that the correct amount of additive is provided. Methods of selecting a fuel using the system hereof are also disclosed.

A delivery system includes a transportation container for cooking oil carried by a delivery vehicle for filling a storage container located at a restaurant. A flexible conduit is temporarily connected between the transportation container and the storage container. The oil is pumped from the transportation container to the storage container. A pressure sensor, carried by the vehicle downstream the pump, monitors pressure in the storage container. A processor operates with the pressure sensor for determining a pressure level in the storage container and controls delivery of the oil for limiting a pressure level to a preselected value. The system waits a period of time and tests the pressure to allow the pressure in the storage container to equalize so that pressure in the conduit at the vehicle is the same as pressure in the storage container. The pressure level is used to establish the amount of cooking oil delivered.

Some embodiments include a mobile fueling system. The mobile fueling system includes a fueling lid configured to cover a fueling compartment opening, and a recessed fueling compartment having the fueling compartment opening. The recessed fueling compartment includes one or more compartment walls having at least one recessed wall portion that is recessed a predetermined distance away from the fueling compartment opening, with the one or more compartment walls defining an interior compartment volume. The recessed fueling compartment further includes a fueling port configured to couple the recessed fueling compartment to a fuel storage tank, and a gas inlet in at least one of the one or more compartment walls of the recessed fueling compartment. The gas inlet is configured to introduce a gas into the interior compartment volume. Other embodiments of related systems and methods are also disclosed.
