The Mazda 3 is a sporty hatchback that gets good gas mileage and has enough room to store all of your family's equipment for outings. It's equipped with a gutsy engine that has a bit of zip to it when you mash the pedal. However, if you are beginning to notice a lag when you depress the accelerator or your Mazda 3 is sputtering, you could have a clogged fuel filter. Luckily, changing a fuel filter is easy.
Crawl under the car near the rear bumper and locate the gas tank (large metal tub-looking protrusion from the bottom of the car). Find the gas line running from the front of the gas tank toward the front of the car.
Follow the gas line until you locate a cylindrical apparatus, which is the fuel filter.
Use the screwdriver to remove the filter from the fuel filter mount, then use the pliers to pull the tubes off of the ends of the fuel filter.
Slide the gas lines onto the proper sides of the new fuel filter, slide the filter back into the mount, and then tighten down the mounting bolts with the screwdriver.
When you start the car up, turn the key to "Accessories On" for 3-5 seconds first, and then turn the car the rest of the way on. This allows the pump to prime the gas line.
