Auxiliary fuel tank systems for aircraft and methods for their manufacture and use. In one embodiment, an aircraft can include a fuselage, at least one engine, and a fuel system configured to distribute fuel to at least one of the engine and an aerial refueling manifold. The aircraft can further include an auxiliary fuel tank system operably coupled to the fuel system. The auxiliary fuel tank system can include a master tank assembly and at least one slave tank assembly. The master tank assembly can be removably installed in the fuselage, and can include a master tank body configured to hold fuel. The master tank body can be configured to pass through a door in the fuselage without disassembly. The slave tank assembly can be removably installed in the fuselage at least proximate to the master tank assembly, and can include a slave tank body configured to hold fuel.

I claim: 1. A method on an aircraft for providing fuel to at least one of an engine and an aerial refueling manifold during flight, the method comprising: at least partially filling a first tank assembly with fuel in a fuselage of the aircraft by flowing fuel through a dual purpose inlet/outlet duct coupled to the first "tank assembly and positioned at least partially withen the first tank assembly;" at least partially filling a second tank assembly with fuel in the fuselage of the aircraft by flowing fuel through the dual purpose inlet/outlet duct; drawing fuel from the first tank assembly by operating a fuel transfer pump positioned in the first tank assembly; while drawing fuel from the first tank assembly, drawing fuel through an inlet positioned in the second tank assembly by operating the fuel transfer pump positioned in the first tank assembly; passing the fuel drawn from the first and second tank assemblies through the fuel transfer pump: and after passing the fuel drawn from the first and second tank assemblies through the fuel transfer pump, flowing the fuel out of the first and second tank assemblies to at least one of the engine and the aerial refueling manifold through the dual purpose inlet/outlet duct, wherein the dual purpose inlet/outlet duct is configured to transfer fuel from, and provide fuel to, the first and second tank assemblies. 2. The method of claim 1, wherein at least partially filling a first tank assembly with fuel includes at least partially filling a first tank assembly removably installed in a fuselage of the aircraft, and wherein at least partially filling a second tank assembly with fuel includes at least partially filling a second tank assembly removably installed in the fuselage at least proximate to the first tank assembly. 3. The method of claim 1, wherein at least partially filling the first and second tank assemblies with fuel before takeoff includes at least approximately simultaneously filling the first tank assembly and the second tank assembly. 4. The method of claim 1, further comprising: removably installing the first tank assembly in a fuselage of the aircraft, the first tank assembly having a first aperture in a first end wall; removably installing the second tank assembly in the fuselage of the aircraft, the second tank assembly having a second aperture in a second end wall, the second end wall of the second tank assembly facing the first end wall of the first tank assembly; and extending a portion of a fuel duct through the first and second apertures. 5. A method on an aircraft for providing fuel to at least one of an engine and an aerial refueling manifold during flight, the method comprising: at least partially filling a first tank assembly with fuel in a fuselage of the aircraft by flowing fuel through a dual purpose inlet/outlet duct coupled to the first "tank assembly and positioned at least partially withen the first tank assembly;" at least partially filling a second tank assembly with fuel in the fuselage of the aircraft by flowing fuel through the dual purpose inlet/outlet duct; drawing fuel from the first tank assembly through a first inlet operably coupled to a first portion of a fuel duct positioned in the first tank assembly; while drawing fuel from the first tank assembly, drawing fuel from the second tank assembly through a second inlet operably coupled to a second portion of the fuel duct positioned in the second tank assembly: passing the fuel drawn from the second tank assembly through the first tank assembly; and after drawing the fuel from the first and second tank assemblies, transferring the fuel drawn from the first and second tank assemblies to at least one of the engine and the aerial refueling manifold through the dual purpose inlet/outlet duct, wherein the dual purpose inlet/outlet duct is configured to transfer fuel from, and provide fuel to, the first and second tank assemblies. 6. The method of claim 5, wherein passing the fuel drawn from the second tank assembly through the first tank assembly includes passing the fuel drawn from the second tank assembly through a tank interconnect bridging a gap between the first and second tank assemblies. 7. The method of claim 5, wherein passing the fuel drawn from the second tank assembly through the first tank assembly includes passing the fuel drawn from the second tank assembly through a first aperture in a first end wall of the first tank assembly and a second aperture in a second end wall of the second tank assembly. 8. A method on an aircraft for providing fuel to at least one of an engine and an aerial refueling manifold during flight, the method comprising: at least partially filling a first tank assembly with fuel in a fuselage of the aircraft by flowing fuel through a dual purpose inlet/outlet duct positioned at least partially within the first tank assembly; at least partially filling a second tank assembly with fuel in the fuselage of the aircraft by flowing fuel through the dual purpose inlet/outlet duct; drawing fuel from the first tank assembly; while drawing fuel from the first tank assembly, drawing fuel from the second tank assembly; and after drawing the fuel from the first and second tank assemblies, transferring the fuel drawn from the first and second tank assemblies to at least one of the engine and the aerial refueling manifold through the dual purpose inlet/outlet duct positioned at least partially within the first tank assembly, wherein the dual purpose inlet/outlet duct is configured to transfer fuel from, and provide fuel to, the first and second tank assemblies. 9. The method of claim 8, wherein drawing fuel from the first tank assembly includes drawing fuel through a first portion of a first outlet duct operably coupled to a first branch of the dual purpose inlet/outlet manifold, and drawing fuel through a second portion of a second outlet duct operably coupled to a second branch of the dual purpose inlet/outlet manifold. 10. A method on an aircraft for providing fuel to at least one of an engine and an aerial refueling manifold during flight, the method comprising: at least partially filling a first tank assembly with fuel in a fuselage of the aircraft; at least partially filling a second tank assembly with fuel in the fuselage of the aircraft; drawing fuel from the first tank assembly; while drawing fuel from the first tank assembly, drawing fuel through an inlet positioned in the second tank assembly by operating a fuel transfer pump positioned in the first tank assembly; passing the fuel drawn from the first and second tank assemblies through the fuel transfer pump; and after passing the fuel drawn from the first and second tank assemblies through the fuel transfer pump, transferring the drawn fuel to at least one of the engine and the aerial refueling manifold through a dual purpose "inlet/outlet duct positioned at least partially within the first tank assembly, wherein the dual purpose inlet/outlet manifold is" configured to transfer fuel from, and provide fuel to, the first and second tank assemblies. 11.
