Google purolite. Then you don't need to worry about your filters failing to catch particles like the Mag. The purolite has other equipment needs but I think it looks promising. I have not used it but I would like to.

Also I recover all the methanol my fuel then let it settle for a few days and the left over soap settle out. Filter thru 1 micron bag filters and use it.

MonsterBaby could you give some specs on those bag housings you built? been looking for some thing like that.
