2. Fuel pump - Wikipedia

   en.wikipedia.org/wiki/Fuel_pump

   In fuel-injected petrol engines, an electric fuel pump is typically located inside the fuel tank. For older port injection and throttle-body injection systems, this "in-tank" fuel pump transports the fuel from the fuel tank to the engine, as well as pressurising the fuel to typically 40–60 psi (3–4 bar).

3. Electric-pump-fed engine - Wikipedia

   en.wikipedia.org/wiki/Electric-pump-fed_engine

   The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...

5. 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%.

6. Holley Performance Products - Wikipedia

   The Dominator also evolved in the 1990s into the HP Dominator; huge billet electric fuel pumps were introduced, and retrofit EFI kits evolved into digital Pro-Jection 4D and 4Di. In 1998 Coltec Industries sold Holley Performance for $100 million to a management-led team backed by Kohlberg & Co., L.L.C. [ 22 ]

7. Vapor lock - Wikipedia

   en.wikipedia.org/wiki/Vapor_lock

   Most modern engines are equipped with fuel injection and have an electric submersible fuel pump in the fuel tank. Moving the fuel pump to the interior of the tank helps prevent vapor lock since the entire fuel-delivery system is under positive pressure and the fuel pump runs cooler than it would be if it is located in the engine compartment.
