I would think anything below 10 micron would damage a Filrite pump. My 15 GPM Filrite pump only pumps about 5 gallons per minute with a 10micron screw on filter attached. I sure wouldn't want to restrict it any more by adding additional filters or finer screens. Your engines fuel filters work great for final filtering and even though they may stop up on rare occasions, they are generally quick and easy to replace.The 2u filter would be nice, especially with the low amount of fuel I will use. However, I have to assume the factory Kubota filter on my equipment is sized accordingly to prevent damage / issues (other than a clogged fuel filter)
2 years on my tank with the same setup. Put the clear bowl first so I can see any water or sediment settling in the bottom (none so far). Then the waterblock batting cleanup ready to clog up & stop flow if any water makes it thriugh.I agree with the don't overthink the issue comments. Mine, as noted earlier, is two filters; one a regular and the other a waterblock. Actually, the waterblock alone would be enough because it also filters. My tanks are inside and in 10 years I can't find any water anywhere.

Personally I'd prefer if my tank was sloped towards rather than away from the filters. That way water starts coming out sooner than later. I have the clear bowl to see any water or junk & the waterblock to stop it from going past. Another valve in the back just means another part to leak or get hit, not to mention worying about checking & draining. Getting water out faster means less rust in the tank long-term.
It plugs up & stops flowing when it's caught to much water. I'm guessing it's coated in the same clear fell stuff they use for baby diapers & flowers. It expands a LOT when it absorbs water. I've heard it doesn't absorb oils.The way I understand the Goldenrod canister waterblock filter to work is that it both separates water plus filters fuel and continues to work until either grit or water fills it to capacity.
Smaller the micron number filter, smaller particles are filtered. That said, a chicken wire screen will eventual "filter" a very small particle. A very important specification is how efficient a filter is at capturing particles of the specified size. I believe your "higher number is better" question is the efficiency specification called the Beta rating. A higher Beta rating means the filter is capturing more particles of the specified size than it is allowing downstream. It may also involve multiple passes of the fluid with the results being averaged, but I don't know that much about the spec. Beta = 2 with say 10 micron particles means the filter captures 50% of 10 micron or larger particles. I think it would be written "Beta 10u = 2".I used to know this but isn't the higher the micron number the smaller the size it will filter?
And , what micron size should we use for a fuel tank? I recall the filters come in different micron sizes.
