Oil & Fuel Micron value of OEM fuel filters on Kubota

[Industrial Toys]

Just looking for answers. Do (some?) oil filters in fact bypass oil if plugged?

Is there not a tradeoff with filtration? Increased filtration means lower flow?

I can't quote a source, but several years ago I tried to find out what the micron rating was for the plastic inline Kubota filters, and found a reference to 50 micron (absolute), 30 micron (nominal).
Whether that's true or not I can't really say with certainty.
I added a very large 2 micron spin on cat filter to my ZD mowers to make the point moot.

On the BX series there are two inline filters, both with the same part numbers.
That doesn't make a lot of sense to me.

They are inline. The second filter is to protect the injectors from a electric lift pump failure (tank > filter 1 > lift pump > filter 2 > injectors)
