Will, I have the same issue and have tried tanks from each year EF, different pumps, etc. all with no luck. One thing I did want to try was running 3-4 of these Walbro fuel pickups I read about on the Sandbox. "Technically" they're 70 micron filters.

The one thing I don't know is if they'll fit through the fuel pump access hole. If they do then you could remove the factory filter/sock from the bottom of the pump, tee off of that, then use a couple 'Y's to branch one to each side/corner of the tank (factory baffling might be a problem).

Feel free to buy one of these and let me know if they fit the fuel pump access hole.
