Where can the fuel filter be found in a 2009 Nissan Sentra?

In a 2009 Nissan Sentra, the fuel filter is located on the fuel tank's left side, close to the frame rail. You can disconnect the filter by using a medium flat blade screwdriver to turn the tabs on the protective cover by 45 degrees for removal. The average cost for replacing this part on the Sentra ranges from $50 to $100, with labor making up $40 to $60 of that total. Doing the replacement yourself can help you save some money. The fuel filter's primary function is to prevent debris from flowing from the fuel tank to the engine's cylinders. A damaged or clogged filter can lead to various issues, including rough idle, starting problems, acceleration issues at low speeds, misfiring, engine hesitation, stalling, strong exhaust odors, noise from the fuel pump, and difficulties with the carburetor and fuel injectors.
