   On engines that use a carburetor (e.g. in older cars, lawnmowers and power tools), a mechanical fuel pump is typically used in order to transfer fuel from the fuel tank into the carburetor. These fuel pumps operate at a relatively low fuel pressure of 10–15 psi (0.7–1.0 bar).

3. Electronic Diesel Control - Wikipedia

   en.wikipedia.org/wiki/Electronic_Diesel_Control

   The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are now primarily fulfilled by ...

4. Rutherford (rocket engine) - Wikipedia

   en.wikipedia.org/wiki/Rutherford_(rocket_engine)

   The pumps (one for the fuel and one for the oxidizer) in electric-pump feed engines are driven by an electric motor. [19] The Rutherford engine uses dual brushless DC electric motors and a lithium polymer battery. It is claimed that this improves efficiency from the 50% of a typical gas-generator cycle to 95%. [20]
