The fuel filter location on a Mazda 3 varies slightly depending on the year and engine. It's
not easily accessible like in some vehicles; it's typically integrated within the fuel pump assembly inside the fuel tank. This means accessing it requires dropping the fuel tank.
Therefore, replacing it is generally a job for a professional mechanic.
You should consult your owner's manual for the specific location and replacement instructions for your Mazda 3's year and model. The manual will give the most accurate and safest information.
