A refueling method for supplying fuel to at least one piece of fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The method includes using a supply coupling device for receiving fuel from one or more supply fuel lines in communication with the main fuel source and providing the fuel to a motor. The method includes using a return coupling device for receiving fuel from the motor and transferring the fuel through one or more return fuel lines to the main fuel source.
