The mechanics of your fuel system

Car fuel system has evolved a staggering amount over the last decade, and the biggest issue that manufacturers addressed with those advancements involves the amount of fuel used by the engine. Consequently, the fuel systems found in modern cars can get pretty complex. Luckily, the most complex ways vehicles save fuel involve programming in the ECU. Physically, there are only a handful of fuel system layouts to be found under the hoods of modern cars. It all begins at the pump. A cars gas tank is responsible for holding a vast majority of gas in the fuel system. The gas first enters the fuel system, the fuel pump is what physically pumps the fuel out of the car gas tank. Some vehicles have more than one pump, it helps in regulating the fuel and a smooth flow. The pump pushes gasoline into the fuel lines. There are hard metal fuel lines in most vehicles that run the fuel from the tank towards the engine. They are run along parts of the vehicle where they will not be too exposed to the elements and will not get too hot from the exhaust or other components. Before it can get to the engine, the gas has to pass through the fuel filter. The fuel filter removes any impurities or debris from the gasoline before it gets into the engine. This is a very important step and a clean fuel filter is key to a long-lasting and clean-running engine. Different parts that make up this fuel system, fuel pump, fuel injectors, fuel lines, gas tank and the brain that controls all this is the ECU or commonly known has the computer box. Electronic fuel injection provides us, as consumers with better fuel mileage and a good performance on the road.
