Where is the fuel filter located on a 2001 Nissan Sentra and how do you replace it?

A 2001 Nissan Sentra (1.8 L engine) has only one fuel filter on the vehicle, which is located inside the gas tank. It is more technically called a "fuel screen". The car does not have an inline fuel filter between the tank and engine like most other cars. Usually, this type of fuel screen does not require periodic replacement. However, if you are replacing the fuel pump, then it is recommended that the fuel filter/screen be changed at the same time.
