I have found the answer to my question

On many vehicles, the

fuel filter is non-serviceable (see table).
The filter is an integral part of the fuel pump module and fuel
pump regulator assembly. The filter can be serviced only by
replacement of the fuel module assembly

. This process requires
the removal of the fuel tank (often one or two hours of labor)
plus several hundred dollars of unnecessary parts.
