I think you might look at the Racor 120A.
Racor at Zorro
It is available with 2, 10, and 20 micron filters. Flow rate I think is 15 gallon per hour. I read an article that suggested 10 micron filters. I would call Racor and discuss it with them. The 120A is supposed to be used on the vacuum side of the pump, making it good for right after the tractor tank. I also saw a thread where one was installed on a Kubota B Series (I think) tractor.
I think the racor is the best way to insure there is no water in your fuel just before it it is used.
I have an L4701. The water separator is not much comfort. I have been wanting to see about installing Racor on my tractor also.
