• fuel recharging means coupled to said lower fuel chamber for periodically recharging said lower chamber with fuel;
• dispensing means for dispensing fuel from said upper fuel chamber into said trunk hoses;
• a plurality of trunk hoses coupled to said chambered fuel silo and extending toward said motorized equipment;
• and
• float valve means coupled between said trunk hoses and each one of said at least one fuel tank.

A refueling system for motorized equipment, said motorized equipment including at least one fuel tank, each of said at least one fuel tank having a tank fuel reservoir and a fuel tank nozzle, the refueling system comprising

• a chambered fuel silo having
• a vertical silo axis extending between a silo bottom and a silo top;
• a silo perimeter coaxial with said silo axis and disposed a select radial distance from said silo axis;
• a lower fuel chamber within said silo perimeter and coaxial with said silo axis, said lower fuel chamber adapted to contain a first volume of fuel;
• an upper fuel chamber within said silo perimeter and disposed axially above said lower fuel chamber, said upper fuel chamber adapted to contain a second volume of fuel;
• refilling means coupled between said lower fuel chamber and said upper fuel chamber and adapted to refill said upper fuel chamber with fuel from said lower fuel chamber;
• fuel recharging means coupled to said lower fuel chamber for periodically recharging said lower chamber with fuel;
• and
• dispensing means for dispensing fuel from said upper fuel chamber;
• a plurality of trunk hoses coupled to said dispensing means and extending toward said motorized equipment;
• and
• a plurality of valve interfaces, one valve interface each coupled between one of said plurality of trunk hoses and said fuel tank reservoir of one of at least one fuel tank, each valve interface having
• a cap adapted to mate with said fuel tank nozzle, said cap including a cap port removably coupled to one of said trunk hoses;
• a valve head having a longitudinal valve axis and coupled coaxially to said cap, said valve head adapted to insert into said fuel tank through said fuel tank nozzle, said valve head having
• a fuel inlet chamber coupled to said cap port and in fluid communication with said trunk hose, said fuel inlet chamber having an outlet port surrounding and defining an outlet port having a valve seat;
• a fuel outlet chamber coupled to said outlet port and in fluid communication with said tank fuel reservoir;
• a plunger coupled between said fuel inlet chamber and said fuel outlet chamber, said plunger having a plunger head adapted to seat within said valve seat and to seal said outlet port, said plunger adapted to articulate between a closed plunger position sealing said outlet port and an open plunger position;
• a float disposed coaxial with said valve head distal said cap, said float having
• a cylindrical float body coaxial with said longitudinal valve axis and a diameter sized to be admitted through said fuel tank nozzle, said float body adapted to articulate axially in response to a level of fuel within said fuel tank reservoir;
• pivot linkage coupled between said float body and said plunger, said pivot linkage adapted to urge said plunger to articulate between said open plunger position and said closed plunger position in response to varying levels of fuel within said fuel reservoir.

The refueling system of claim 17 wherein

• said chambered fuel silo further includes
• a base coupled to said silo bottom below said lower fuel chamber, said base adapted to support said chambered fuel silo in a vertical position, said base having
• at least three legs arrayed coaxially around and extending parallel to said silo axis a spaced distance below said silo bottom;
• and
• a platform disposed on said at least three legs distal said silo bottom;
• and
• said gantry is adapted to erect said chambered fuel silo in said vertical operating position supported on said platform.

A method of simultaneously fueling multiple units of motorized equipment, each unit of said motorized equipment having at least one fuel tank, said at least one fuel tank having a fuel tank reservoir and a fuel tank nozzle, the method comprising

• providing a chambered fuel silo having
• a vertical silo axis extending between a silo bottom and a silo top, said silo axis surrounded with a coaxial silo perimeter disposed a select radial distance from said silo axis;
• a lower fuel chamber within said silo perimeter and adapted to contain a first volume of fuel;
• an upper fuel chamber within said silo perimeter and disposed axially above said lower fuel chamber, said upper fuel chamber adapted to contain a second volume of fuel;
• refilling means coupled between said lower fuel chamber and said upper fuel chamber for refilling said upper fuel chamber with fuel from said lower fuel chamber;
• and
• dispensing means for dispensing fuel from said upper fuel chamber;
• providing a plurality of trunk hoses;
• and
• providing a plurality of float valves adapted to be received within said at least one fuel tank nozzle;
• erecting said chambered fuel silo proximate said multiple units of motorized equipment with its vertical axis disposed vertically;
• then
• installing one of said plurality of float valves into said fuel tank nozzles on each of said at least one fuel tank on each of said multiple units of motorized equipment;
• then
• coupling said plurality of trunk hoses between said dispensing means and said float valves;
• then
• operating said dispensing means to dispense fuel from said upper fuel chamber into said at least one fuel tank;
• and
• maintaining said second volume of fuel by periodically monitoring its level in said upper fuel chamber and refilling said upper fuel chamber with fuel from said lower fuel chamber.
