Hah thanks, I'll remember that should it leave me stranded.

Yeah, I've read about those. Also not the only higher-mileage owner to say their tank was clean inside. Leaves me completely baffled, I know the fuel filter had an immediate and enormous benefit but I can't imagine changing something downstream of the fuel tank would have helped if the pump itself was starving over a clogged filter sock. And if the tank isn't starving for fuel and the original filter was clogged, how did it clog again so quickly?
I will say that I've probably run the tank low a lot.. I was under the assumption that inaccurate gas gauge and crappy tank venting caused me to fill up with a few gallons left in the tank after riding the gas light for a ways, always. Further reading just the other week suggested that the tank vent tube is too long and there's likely very little gas left when I'm filling ~14 gallons.
I've never taken my 4runner anywhere to be serviced, short of Discount Tire and Firestone for alignments, but I'd happily pay for a pro to get to the bottom of this. I had a brief taste of what a properly running 4runner feels like and it'd be so worth the bill to have that consistently, but I don't know what kind of troubleshooting a pro would do that I can't, just out of ideas.
