Where is the fuel filter located on a Mazda 121?

Oh, dude, the fuel filter on a Mazda 121 is usually located along the fuel line, somewhere between the gas tank and the engine. It's like a ninja hiding in the shadows, silently filtering out all the gunk from your fuel. Just remember, if you're gonna go searching for it, maybe bring a flashlight and some snacks, it could be a wild adventure.
