I also read somewhere that our fuel filters have some sort of built in water separator in them with an unknown capacity. I will try and find the link, but is there any truth to this and would it matter? I'm guessing not or you would be using XPD.

There is a min amount. It's measured in combination with sediment and is .05% (ATSM D2709).
