E85 compatible fuel filter

[SlowWhite]

Basic question is, my filter come to find out is almost 3yrs old and was never changed when previous owner switched to E85. And from research switching to E85 can clean out all the junk that built up in your fuel tank over the years.
I have been fighting a part throttle issue and I have a new isc and tps sensors on the way but want to change the filter as well.

My question:
Research shows SS element is the way to go but what is the best micron size and filter to go with seeing as this car will mostly be running 93oct. But i want the car to be fully set up to run E85. I plan tp buy from "map" and will be -6 I/O
