Your sedan requires plenty of clean fuel to run. When your fuel isn’t clean, your fuel injectors can start to become clogged up. When this happens, your sedan engine may not get the proper amount of fuel at the correct pressure to run efficiently. This hurts fuel economy and performance as you drive around Los Angeles. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.
That’s why all vehicles, including sedans, come equipped with a fuel filter somewhere between the engine and the fuel tank. 
The job of the filter is to clean out little pieces of dirt and contamination. The filter captrues the contaminants and holds them out of the fuel stream. Of course, the filter will eventually get clogged up and need to be replaced at AutoAid & Rescue.
If your fuel filter is clogged, the sedan engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your engine running, but doesn’t protect it from contaminated fuel.
You may find that you need to change your fuel filter at AutoAid & Rescue more frequently as your sedan ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel economy.
