3 Types of Fuel Pumps and How They Work 3 Types of Fuel Pumps and How They Work
There are three main types of fuel pumps that you will be able to find. Each has its own way of working its own qualities. It is important that you are able to know which one does what so that you will get the right one for you. That is why it is important to do your homework and shop around. It can be tricky to find the right one for you. Make sure you know if you will need a fuel pump that will pump the gas into a carburetor or into the fuel injection system. Know what the differences are and what they can accomplish for you.
Mechanical Fuel Pump
The mechanical fuel pump is one that is most often used with engines that use a carburetor. Back before fuel pumps became a necessity for cars, the fuel was fed directly into the carburetor. This was done through the act of gravity. They are on their way out as they pump fuel at very low pressure rates. Over time they are being used less and less, most exclusively in older cars. Pretty much any new or even newer car is not going to use this type of fuel pump. Eventually they will be completely phased out as newer cars do not require them at all.
Because the mechanical fuel pump pumps the fuel into the carburetor, this slows down the efficiency of the fuel delivery. The fuel injection has become the more contemporary source with cars. The fuel is pumped at a higher pressure and will help to deliver the fuel in the most efficient way possible.
Electric Fuel Pump
The electric fuel pump is the most commonly used fuel pump that you will find. It is slowly taking over the place of the mechanical fuel pump. You will find that the electric fuel pump is located directly inside the fuel tank. In comparison to the mechanical fuel pump, the electric fuel pump pumps gas to the fuel injection system at a much higher pressure. Because of this they are slowly taking over and are found in most new or newer cars as opposed to the mechanical fuel pump.
The electric fuel pump works with the fuel injector in the car. It helps to get the fuel going where it needs to quicker and easier. Because of this, it obviously is the more desired choice when it comes to fuel pumps.
You will not often find a turbo pump being used in an automobile. They are very large and are normally reserved for a more high volume engine type. Typically, you will more often than not see these types of fuel pumps on a jet or something of that nature. They will over time become more popular as technology allows for more research to be done and the parts to make them become less expensive. They are still very large pumps and will not be used for your typical automobile or a smaller engine as they are much too powerful to work properly.
