Liquid Fuel is a fuel type commonly used by rocket engines.

Other fuel types in the game are Jet Fuel, RCS Fuel and Solid Fuel.


Fuel Containers

Liquid fuel can be pumped from a fuel tank to another fuel tank or engine connected via an FTX-2 External Fuel Duct.
The following tanks contain Liquid Fuel.

Liquid fuel and oxidizer density are both 5 kg/unit Mass
