I was looking at something like this yesterday afternoon:

Not too trilled with the price, but it does fit the frame of mind I have about what how I want to filter the wvo at the house. I would be happy if I could come up with some filters (enclosed/spin on) that allow step filtering...200 micron over the first drum, heat & settle the oil, pump it through a 50 micron filter, leading to a 10 then 1 micron before oil goes to the holding tank. Another pump (with meter) would push it through a nozzle and into the tank on the truck. Figuring I need another 1 micron between the tank and the motor to catch what ever might get into the tank during fueling.
