A fuel pump pushes the fuel from the tank through fuel lines and conveys it into a fuel filter. The main part of the fuel system is the fuel tank. Standard fuel tanks contain fuel filler pipe, a fuel outlet line to the engine, and a vent system. Fuel lines, made of metal or rubber hoses transmit the fuel from the fuel tank to the combustion engine.

Another part of the fuel system is the fuel pump. Most of the modern fuel systems like Jaguar fuel system parts utilize two different types of fuel pumps, the mechanical and electric fuel pump. Fuel injected cars use electric fuel pumps, while most cars that use carburetors are equipped with mechanical fuel pumps.
