I'd say leave it alone unless you get a lean code. The Toyota sites have many "woe is me" tales about trying to replace fuel filters and causing broken or twisted fuel lines. Auto gas is a lot cleaner than it once was, even the FAA agrees. For reference, one of my Camrys still has the OEM filter at 350K. Getting the bottom connection off the Camry filter is a problem, even the stealers are not happy to get into the task. If the "technician" damages your fuel line trying to get the filter off, YOU pay for replacing the entire line, stealers won't just splice in a hunk of rubber fuel hose..I can't say I blame them. The system used by Toyota on their post mid 90 cars is a single pipe system which does not return fuel to the tank, unlike the old "shunt regulated" system where fuel was constantly pumped up front at full output and the excess returned to the tank to be pumped up front again. That resulted in the filter seeing the same fuel over and over, and the filters were large. The regulator for the single pipe system is in the tank, right at the pump. Only the fuel actually used is filtered.
