How Does An Electric Fuel Pump Work?

Are you wondering if your car needs an electric fuel pump? Almost every car built after the late 1980s is equipped with one since these devices are essential for the proper functioning of your vehicle. So how exactly do they work? And what are the benefits of having one installed? Let’s take a closer look.

An electric fuel pump is used in engines to generate pressure in order for fuel to spray out of the fuel injectors when they are open. It’s necessary for the pump to deliver the fuel under high pressure so the injectors can spray fuel directly into the engine. The fuel pressure must be within the proper range for a vehicle to perform correctly. Too little fuel pressure can cause misfires and stalls, while too much of it can cause wastage and extra pollution.

Traditionally, electric fuel pumps are mounted inside the tank since submerging the pump in gasoline is very important. Without the proper supply, a pump can stop working altogether. Fuel pumps can spin at upwards of 4000 RPM, which makes submersion all the more necessary for lubrication and the cooling of the fuel itself.
