Where is the fuel filter located in a 1990 Ford Laser glx?

The fuel filter location on a 1990 Ford Laser GLX (which is essentially a Mazda 323 in most markets) is typically within the fuel tank itself. This was common practice for many cars of that era. It's not a serviceable filter that you'd easily access and replace. The entire fuel pump assembly, which includes the filter, usually needs to be removed and replaced as one unit.
