Types of Electric Fuel Pumps
The most common type of fuel pump is an in-tank electric fuel pump. This type of pump is located within the fuel tank, and uses an electromagnetic motor to move fuel to the engine. This type of pump is generally much quieter than its mechanical counterpart and requires less power to operate. The downside to these pumps is their inability to provide the same level of fuel pressure as a mechanical pump. These pumps typically require a muffler attached to the fuel line to prevent them from leaking fuel.
While the in-tank pumps are the most popular, they aren’t the only option. Electric fuel pumps can also be used with carburetors. However, you should ensure that the type you choose is designed for carburetors. In addition, be sure to mount your electric fuel pump as low as possible and as close to the fuel tank as possible.
There are two types of electric fuel pumps: mechanical and electronic pumps. In a mechanical pump, the diaphragm and armature are connected to one another by a pull rod. The pump sends fuel through the fuel line to the carburetor. With an electric fuel pump, the diaphragm moves up and down, which creates suction. An electric motor drives the pump’s impeller, pushing fuel through the fuel line to the carburetors.
Another difference between an electric and a mechanical pump is that an electric fuel pump may work with either gasoline or diesel. Electric pumps usually have an output pressure rating of 3 to 6psi, a pigtail for power, and clear indicators. Some models even come with a mounting bracket and an easy-to-read indicator that will indicate how much pressure the pump is delivering.
