The internal combustion engine has always been regarded as an ingenious invention which has actually played a huge role in bringing about the industrial revolution. And to go a step further, this invention human race to move into the world of automobiles. The first ever fuel run vehicle was developed with this engine itself. And look at how far we have come today. Cars of this era are mind boggling machines that move with extraordinary power. And this power becomes possible thanks to electric fuel pumps.

The fuel pump is one of the essential parts of a vehicle's fuel delivery system. Its main purpose is to draw fuel from the fuel tank and supply it to the engine. Without this device, any car would simply not have the energy to move forward! In older times, there were mechanical fuel pumps that made cars work. But these days, almost all cars some equipped with electric fuel pumps that deliver the power desired to make these dream machines run.

If your car has an electronic fuel injection system, it means that there is an electric fuel pump installed in it to feed the necessary power to its engine. They operate more efficiently and deliver higher pressure (40-60psi). By placing the pump inside the fuel tank itself, appropriate temperature is maintained to enhance the efficient working of the overall system of your car. Let us look closely at the functioning of an electric fuel pump.

You can assume its working to be quite similar to a mechanical fuel pump. The electric pump also has the check valve and diaphragm pull system, but the pull on the diaphragm is provided by an electric switch also called the 'solenoid’. The diaphragm is actually attached to an iron rod which forms the connection between it and the solenoid. By making use of electromotive force, the solenoid manages to attract the iron rod towards itself, pulling the diaphragm down and allowing the fuel to enter into the chamber. When this happens, the solenoid pulls apart the contacts through which electricity passes which shuts down the flow of electricity. This initiates the attached spring to pull the diaphragm back into its original position, which causes the fuel to get pumped into the outlet valve. When the outlet valve enables this flow of fuel, the electric current is restored and the process begins all over again.

This basic system allows the fuel to get injected into the vehicle’s engine which is then combusted and converted into energy utilised to move forward. When you compare the electric fuel pump to its mechanical counterpart, you will find the former to be safer, more convenient, durable, and resistant to contamination and capable of ensuring optimal fuel efficiency. However there are still people who prefer the mechanical pumps owing to their ease of installation and the chance to avoid any electrical issues with the vehicle.
