The most important role of a fuel delivery system is to supply fuel even in an emergency situation.
Main components: A typical fuel delivery system consists of various components such as tank, pump, pipe, in-filters, strainers, injectors, pressure regulators, return pipe, pulsation damper, etc. Here, we will discuss only the vital components of the system.

Fuel tank: A fuel tank, as we all know, stores the fuel in a location, away from the engine. These are constructed using different materials like pressed corrosion-resistant steel, aluminum, or molded reinforced polyethylene plastic.
Many modern tanks incorporate slosh baffles or surge plates, which prevent the fuel from splashing around inside the unit.
The tank also has a filter (to filter the fuel) and a vent system with an inlet line (through which fuel from the cap enters the tank) and an outlet line (to send the pumped fuel to the engine).
Fuel pump: It is often called the heart of the fuel delivery system. Its main function is to pull the fuel from the tank and to pump it to the injectors at the required pressure.
Many of the modern engines are equipped with electric pumps that are usually located inside the tank. We can still find mechanical pumps in the old styled carburetor engines.
The basic difference between them is, electric pumps generate high pressure, whereas, mechanical pumps generate low pressure. However, there are some new models of mechanical pumps that pump at high pressures.
