Default Fuel filter location

I cannot find the fuel filter on an 03 Coupe w/ auto trans. I’ve replaced the filter on an 02 w/ 6 spd. and that was an easy job.
The car is jacked up, rear driver’s side wheel removed. The usual location of the filter is not there. Is there another place to look?

This is where the fuel filter should be located. Obviously, it’s not there.

If your 03 is a later model with the RPO code FFS (sticker in your glove box) the fuel filter is part of the fuel pump assembly and is not external.

Thank you so much. The car does have the FFS code. No wonder I couldn’t find the fuel filter.
