No need to replace that filter, for you won't gain anything anyways. (unless you are dealing with a fuel pump replacement issues, then might as well start off with a new sock).
I've replaced a corolla and a sentra fuel sock before (returnless), both had over 200k in the odo. Other than a couple of pieces of large debris trapped on the socks, nothing interesting to see in them and they are still clear (no clogging).
To my understanding: fuel delivery system (from refineries to gas station pump dispenser, etc.) had come a long way during the past decade or so, driven by automobile technologies (returnless fuel pump systems, etc.)...so fuel is essentially much more debris-free nowadays.
(*that is also the reason why I've seen so many local gas stations retrofitting their underground steel tank into poly or fibreglass tanks during the past decade or so, partly due to aging (rusty as the steel tank ages), partly due to newer requirements.
Thanks Quest, my Sentra (2001 1.8L) had nearly 250k miles and its original fuel pump/assembly , on my Camry I am able to see the fuel filter but understand that it's a bit difficult tp remove, I think I'll just leave it alone as it sounds like the pump sock is doing its job.
