I have a pump that circulates the oil through two filters to progressively filter it from 25 microns and then 5 microns. After settling its filtered for enough time to (hopefully) ensure all the oil has passed through the filters two or three times, then I switch a valve and it runs through the filters one final time and is dumped into the holding tank. On the final pass, I restrict the volume of oil after the pump so it goes through slowly, probably a gallon per minute or so.
What do you mean by 6 port or 3 port? Is that a switching valve autozone carries that is factory for some car?

OK well I do a hot pan test with each batch of oil just to make sure it is water free, it is easy and it gives me confidence.
I plan on buying a centrifuge for my filtering needs when I sell the Volvo, the TDI is a bit more picky and I dont want to risk anything. Properly running a centrifuge will take you down to 1 micron
As for valves, I have a diesel send and return at the valve, a veg send and return at the valve and a send and return to the IP. I have it all built into one valve, hence 6 ports.
What I will do to the TDI, and recommend (REALLY) is using two 3 ports valves. One will have the diesel send and veg send and hook to the IP in, the other will have the diesel return, veg return, and hook to the IP return. This way when you switch from veg back to diesel before you shut down, you can purge the return lines back to the veg tank for a few seconds until diesel gets to the veg tank. This assures that you dont empty the little bit of veg that is in the return lines on the injectors into the diesel tank. It is only a little bit but after a while, and in the cold, you will notice it.
Let me know if you have any other questions or if I didnt make enough sense.
