How Does a Fuel Pump Work?

The fuel pump is an essential component mounted in your car's fuel tank. It ensures a consistent supply of fuel to the engine. Modern vehicles use two main types of fuel systems:

Continuous Return Fuel System :

In older vehicles, excess fuel is routed back to the tank using a return line. A pressure regulator maintains the correct pressure within the fuel rail.

Return-less Fuel System

Most modern vehicles feature this design, where fuel pressure is regulated within the tank itself. This system eliminates the need for a return line and offers better fuel control and reduced emissions.

At MyMechanic, we work with both fuel system designs and are equipped to handle repairs for vehicles of all makes and models.
