Fuel tank
Liquid Fuel tanks hold fuel for both rocket engines and jet engines. In real rocket engines, the fuel tanks would need to store both something to burn, usually hydrogen, and some sort of oxidiser, usually oxygen; both stored in liquid forms of course. However Jet Engines only require a fuel, almost exclusively a hydro-carbon similar to what you would use in your car, for they use the air in the atmosphere to burn said fuel.
At present, all fuel tanks in the game can provide both Rocket and Jet fuel, with no need to manage these details your self, it is as if the jet engines within the game are able to run on the same fuel mixture that rocket engines use.
A liquid fuel tank can provide fuel to any engine directly attached to it and when tanks are directly connected together in a stack, they will feed fuel from the top tank first, automatically switching to the next tank as they empty. You can mount additional fuel tanks with radial decouplers, and the use fuel lines to provide fuel into the central tanks. This can be used to provide an 'onion peel' system where outer tanks are drained first, then dumped leaving central tanks completely full. This can be tricky to get set up when dealing with very large rockets, as the out layers need to be kept burning long enough to ensure the rest of the rocket can get into orbit once they have stopped providing thrust.
Liquid fuel and oxidizer density are both 5 kg/unit | Mass (t) |

Note that not only are the the above four dedicated fuel tanks, but there is a selection of Fuselage parts. These parts are intended for space planes and/or shuttles, but can be used as part of normal rocket if desired.

- ↑ 1.0 1.1 1.2 The Engine Nacelle, Engine Pre-cooler, and Mk1 Diverterless Supersonic Intake are a combination of air intake and liquid fuel tank. Only the tank properties are shown. They are located in the "Aerodynamic" category in the game.
- ↑ 2.0 2.1 2.2 The FAT-455 Aeroplane Main Wing, Big-S Wing Strake, and Big-S Delta Wing are a combination of lifting surface and liquid fuel tank. Only the tank properties are shown. They are located in the "Aerodynamic" category in the game.
You can see from the table of dedicated fuel tanks that 200 units of fuel is given a mass of one Kg. However, this value does not extend to the fuselage parts.
It should be noted though that RCS uses its own type of fuel that is separate to Rocket/Jet fuel.
