1. A pumpless, self-contained portable fuel delivery system for delivery of a liquid fuel at remote locations, installed within a vehicle or upon a trailer and requiring no external or internal power supply in the delivery of said liquid fuel, said fuel delivery system comprising: a liquid fuel container having a pressure capacity of at least 200 psi and defining a large capacity cavity containing a liquid fuel;a large capacity air tank having a pressure capacity of at least 200 psi and containing a quantity of compressed air or gas;a first line attached to a top portion of said fuel container, said first line entering said fuel container and further providing a first extension having a first ball valve and extending with an attaching cap, said first extension used for filling said fuel container with a liquid fuel, and a second extension containing a second ball valve, an air pressure regulator and pressure gauge and extending an air check valve with a quick coupling for introducing said compressed air or gas into said fuel container;an air hose attached between a shutoff valve and pressure gauge attached to said air tank and said quick coupling on said second extension;a second line attached through said top portion of said fuel container containing a third ball valve for ventilating said fuel container during filling said fuel container with liquid fuel; anda third line providing a wet leg extension attached through said top portion of said fuel container, having a lower end extending from a location above said bottom portion of said large capacity cavity, said wet leg extension further extending an upper end above said top portion of said fuel container, said upper end further attaching a fourth ball valve, an in-line liquid fuel filter and further extending, a flexible extraction hose including a pump handle with an automatic shutoff and manually depressed dispensing valve, wherein said fuel delivery system contains no pumps which can clog or fail, contains no internal or external power supply for operation which may become exhausted, spent or otherwise fail, utilizing nothing more than cheap and affordable compressed pressurized air to operate said entire fuel delivery system. 2. The fuel delivery system as disclosed in claim 1, wherein said wet leg wet leg extension is extended into said fuel container to within a half inch from said bottom portion of said cavity of said fuel container, allowing for extraction of most of said liquid fuel within said fuel container, and without being fully extended to said bottom portion of said cavity which could result in a restriction to a flow of said liquid fuel from said bottom end of said wet leg extension or could cause a cessation of flow of said liquid fuel from said cavity due to a build-up of inevitably present particulate materials within said liquid fuel introduced into said cavity over time from an environment within which said fuel delivery system is used. 3. The fuel delivery system as disclosed in claim 1, wherein said first ball valve, second ball valve, third ball valve, said first line, second line and third line are all made with 1½ inch fittings and diameters and said air hose, air pressure regulator, pressure gauge, air check valve and quick coupling are provided as ⅜-½ inch lines and fittings. 4. The fuel delivery system as disclosed in claim 1, further comprising said air tank is at least 100 gallon capacity and filled to no less than 150 lbs of pressure with said air regulator set at 30 psi, and said fuel container is at least 500 gallon capacity. 5. The fuel delivery system as disclosed in claim 1, wherein said first ball valve, second ball valve, third ball valve, said first line, second line and third line are all made with 1½ inch fittings and diameters and said air hose, air pressure regulator, pressure gauge, air check valve and quick coupling are provided as ⅜-½ inch lines and fittings; and said air tank is at least 100 gallon capacity and filled to no less than 150 lbs of pressure with said air regulator set at 30 psi, and said fuel container is at least 500 gallon capacity, wherein said fuel delivery system is able to deliver 500 gallons of filtered fuel at a rate of 40 gallons per minute with a minimum operating pressure for the fuel delivery system at 30 psi or above.
