Fuel Filter Change Interval

I change oil/filter every year, fuel filters every other year.

Basic recommendation is every oil change interval OR if you see issues in the primary filter (water, dirt, algae, etc) before that.

This is for the two filter systems. For those with only a single 2 micron filter, it WILL clog up a lot quicker than those with a 10/30 micron primary and 2 micron secondary filter.
