Where is the fuel filter at on a 2006 Chevy Cobalt 2.2?

On a 2006 Chevy Cobalt 2.2L engine, the fuel filter is located inside the fuel pump module, which is inside the fuel tank. This means you can't access it without dropping the fuel tank. It's not a serviceable filter that you can replace individually; you typically replace the entire fuel pump module assembly when the filter needs replacing.
