How does the lift pump work on a Cummins?

The task of the lift pump is to pump fuel. This lift pump is situated where the fuel tank of your vehicle is. By using a vacuum or a DC motor, the lift pump pulls fuel oils from the oil tank, pumps it with high pressure, and sends it to the injector lines to create a spark and, consequently, a burning to run the engine.
