Oil & Fuel B series fuel filters

[kuboman]

Can anyone tell me with any informed authority what the micron rating of Kubota's fuel filters are for there B tractors? They seem pathetically small and inadequate for the job. Maybe they have a low micron rating but if they do then they would not last very long.

Im not sure what the micron rating is but i changed the fuel filters on my B series tractors every 100 hours and could have gone longer from the looks of them?
