You have a in tank fuel pump with a, "Screen sock" type filter.
There is always a filter before the pump and in the case of drop ins, the filter can only be replaced when the tank is dropped, fuel pump removed and then the filter can be replaced.
It is designed for the life of the vehicle and I have seen plenty of them go well past 200,000 miles without issue.
Let me know if I can help you out any more.
