What steps and how do I change the fuel filter in my 2010 Honda Civic?

Albert Miller, it is bundled with the fuel pump, pressure regulator, and fuel level sending unit in the gas tank. There is an access panel in the trunk in the middle of the floor right behind the rear seats

Gasoline is pretty clean these days so there’s little reason to change the filter unless you have a specific reason.
