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 valve element to stop fuel flow from the fuel tank when the main fuel source supplies the fuel to the supply coupling device and allows fuel flow from the fuel tank to the at least one pressurization unit when a system failure prevents the main fuel source from supplying fuel to the supply coupling device and using the return fuel line with the return coupling device for the transfer of the fuel to the fuel tank when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device.

1. A refueling method for supplying fuel to at least one piece of fracturing equipment, the method comprising: a) installing a main fuel source at a fractionation operation, wherein the main fuel source contains the fuel;b) fluidly connecting the main fuel source to the at least one piece of fracturing equipment, wherein the at least one piece of fracturing equipment provides downhole fluids to a well;c) fluidly connecting at least one pressurization unit to the main fuel source, wherein the at least one pressurization unit comprises: i. a fuel tank containing the fuel;ii. a valve element in fluid communication with the fuel tank;iii. a supply coupling device in fluid communication with the valve element, the supply coupling device for receiving the fuel from one or more supply fuel lines in fluid communication with the main fuel source and providing the fuel to an onboard motor;iv. a return coupling device for receiving the fuel from the onboard motor and transferring the fuel through one or more return fuel lines to the main fuel source; andv. at least one fuel pressure regulator, wherein the at least one fuel pressure regulator is in fluid communication with the one or more supply fuel lines and the supply coupling device for reducing fuel pressure coming from the one or more supply fuel lines;d) using the valve element to stop a fuel flow from the fuel tank when the main fuel source supplies the fuel to the supply coupling device and allows the fuel flow from the fuel tank to the at least one pressurization unit when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device; ande) using the one or more return fuel lines with the return coupling device for the transfer of the fuel to the fuel tank when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device. 2. The refueling method of claim 1, comprising using a first quick disconnect having a first quick disconnect fitting mating to a second quick disconnect fitting for an accelerated set up and take down of the refueling unit. 3. The refueling method of claim 2, comprising using a second quick disconnect having an additional first quick disconnect fitting mating to an additional second quick disconnect fitting for accelerated set up and take down of the refueling unit. 4. The refueling method of claim 1, comprising installing a manifold between the one or more supply fuel lines and the main fuel source connected to multiple supply fuel lines enabling the at least one piece of fracturing equipment per supply fuel line to be refueled per line. 5. The refueling method of claim 4, further comprising installing a main fuel source pump connected to the main fuel source for pumping the fuel from the main fuel source through a filter to the manifold. 6. The refueling method of claim 1, wherein the valve element is a check valve, a spring loaded check valve, a ball valve, a two way valve, a shuttle valve, a butterfly valve, a gate valve, or a three way valve. 7. The refueling method of claim 1, comprising mounting a heat exchanger to the main fuel source to receive the fuel from the main fuel source and continuously regulate the temperature of the fuel at to an optimal operating temperature for the onboard motor. 8. The refueling method of claim 1, comprising installing a controller containing at least one processor in the at least one pressurization unit and connecting the at least one processor to sensors installed on the one or more supply fuel lines and sensors installed on the one or more return fuel lines, using the at least one processor to receive flow rate information and pressure information and to compare the flow rate information and pressure information to preset limits in a data storage connected to the at least one processor, and then transmit a message when the flow rate information and pressure information falls below or exceeds the preset limits to a client device via a network to enable a user to adjust rates of operation. 9. The refueling method of claim 5, comprising using the filter to remove particulates, water and water based contaminates flowing through the filter. 10. The refueling method of claim 8, wherein the controller comprises: a) at least one supply sensor in the one or more supply fuel lines;b) at least one return sensor in the one or more return fuel lines;c) the at least one processor configured to receive data from the at least one supply sensor, the at least one return sensor, or from both the at least one supply sensor and the at least one return sensor;d) the data storage in communication with the at least one processor;e) computer instructions in the data storage to instruct the at least one processor to receive the flow rate information and pressure information from the at least one supply sensor, the at least one return sensor, or from both the at least one supply sensor and the at least one return sensor;f) preset pressures for the fuel flow and preset temperature limits for the fuel in the data storage as preset pressure and preset temperature limits;g) computer instructions in the data storage to instruct the at least one processor to compare the flow rate information and pressure information from the at least one supply sensor, the at least one return sensor, or from both the at least one supply sensor and the at least one return sensor to the preset pressure and the preset temperature limits; andh) computer instructions in the data storage to instruct the at least one processor to transmit a message when the flow rate information and pressure information falls below or exceeds the preset pressure and preset temperature limits in the data storage enabling an operator to adjust the rates of the operation of the at least one pressurization unit. 11. The refueling method of claim 1, wherein the valve element has at least one sensor for sensing when the preset pressure and preset temperature limits fall below or exceed the preset pressure and preset temperature limits, actuating the valve element to change the flow of the fuel from the main fuel source to the fuel tank. 12. A refueling method for supplying fuel to at least one piece of fracturing equipment, the method comprising: a) installing a main fuel source at a fractionation operation, wherein the main fuel source contains the fuel;b) fluidly connecting the main fuel source to the at least one piece of fracturing equipment, wherein the at least one piece of fracturing equipment provides downhole fluids to a well;c) fluidly connecting at least one pressurization unit to the main fuel source, wherein the at least one pressurization unit comprises: i. a supply coupling device connected to an onboard motor, the supply coupling device for receiving the fuel from the main fuel source through one or more supply fuel lines from the main fuel source; andii. a return coupling device for receiving the fuel from the onboard motor and transferring the fuel through one or more return fuel lines to the main fuel source;d) using gravity to feed the fuel from the supply coupling device to the onboard motor; ande) using the one or more return fuel lines with the return coupling device for the transfer of the fuel to the main fuel source.
