What is a Electric Fuel Pump

Because the fuel tank is located on the opposite end of the car from the engine, a fuel pump is required to draw the gas toward the engine. There are two kinds: mechanical, which were used in carbureted cars, and electric, which is used in cars with electronic fuel injection.

A carburetor is a fuel delivery mechanism that makes use of the simple principle of vacuum in order to deliver fuel to the engine. The same vacuum that draws the air-fuel mixture into the engine also draws fuel along the lines toward the engine. However, additional help is necessary, so carbureted engines have a mechanical fuel pump. This runs off of the engine's rotation; as a result, in a carbureted machine it is located alongside the engine.

Electronic fuel injection is a delivery system that squirts a fine mist of fuel into the combustion chambers of the engine. A computer controls the system, closely monitoring factors such as the position of the throttle, the air-fuel ratio, and the contents of the exhaust. Because the system does not use a pre-existing force, such as vacuum, to draw the fuel along the lines, the fuel pump must be located at the source — that is, inside or next to the fuel tank itself. The pump is electronic, meaning that it is powered and controlled electronically. Sometimes, its operation can be identified by a soft, steady humming sound coming from the rear of the machine.
