What is an Electric Fuel Pump, and Why is it Necessary?

An electric fuel pump is a device that pumps fuel from the gas tank to the injectors. It is suitable for fuel injected engines. High pressure is required for fuel to be effectively sprayed into the engine. When the pressure is low, your engine could thirst for fuel, which translates to hesitating effects, misfiring, and stalling, leading to poor engine performance.

High pressure also translates to a fuel-consuming engine, which becomes an expensive burden to the car owner. Therefore, a functioning quality electric fuel pump will maintain the balance between extraordinarily high and low pressure.

There are different types of electric fuel pumps;

  • Gerotor pump.
  • Roller cell pump
  • Roller vane pump
  • Turbine style fuel pump

Below are the top 5 electric fuel pumps you should consider for your engine.
