Fuel system

The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air, vaporized, and burned to produce energy. The fuel, which can be either gasoline or diesel is stored in a fuel tank. A fuel pump draws the fuel from the tank through fuel lines and delivers it through a fuel filter to either a carburetor or fuel injector, then to the cylinder chamber for combustion. Tank location and design are always a compromise with available space. Most automobiles have a single tank located in the rear of the vehicle. All tanks have a fuel filter pipe, a fuel outlet line to the engine and a vent system. All fuel tanks must be vented. Steel lines and flexible hoses carry the fuel from the tank to the engine. Two types of fuel pumps are used in automobiles: mechanical and electric. All fuel injected cars today use electric fuel pumps, while most cars with carburetors use mechanical fuel pumps. Many cars today locate the fuel pump inside the fuel tank. While mechanical pumps operate on pressures of 4–6 psi (pounds per square inch), electric pumps can operate on pressures of 30–40 psi. The fuel filter is the key to a properly functioning fuel delivery system. This is more true with fuel injection than with cars with carburetors. Fuel injectors are more susceptible to damage from dirt because of their close tolerances, but also fuel injected cars use electric fuel pumps. When the filter clogs, the electric fuel pump works so hard to push past the filter, that it burns itself up. Most cars use two filters. One inside the gas tank and one in a line to the fuel injectors or carburetor.
