found in multi-engine aircraft are:

Each wing tank often has its own electric boost fuel pump, and each engine has its own mechanical pump, replicating the fuel system described above for the single engine.
In case of single-engine operation, there is often a method incorporated to "cross-feed" the engine (left tank feeding right engine, or vice versa).
To balance asymmetric weight, flow valves and pumps often are used to feed both engines from one tank or simply to transfer fuel between tanks.

Turbine fuel system
All of the considerations made for the twin piston are applicable to turbine fuel systems. Additional consideration apply because of the higher altitudes, different fuel, lower temperatures, and longer flights.

To avoid water condensation or the fuel itself solidifying at low temperatures (-55 °C), fuel tanks have thermometers and heatingParker Leavitt
