My filtration system:
All oil comes in here, the igloo works quite well, the outlet is about 1.5" up off the bottom so any water lays there instead of going through the filters. It also has gallon markings to allow me to get close to mix percentages I want. The Valves are set to either pick up from a 5 gallon bucket or pull from either one of the two holding barrels for a second filtration to go to the final barrel for mixing with #2
These are the filters, a dual oil filter relocation kit works well with a set of 10 micron fuel filters and also serves to get out the bigger stuff from the oil, the next single filter is the 2 micron fuel/water seperator. Then from there it goes to a holding barrel or to the final barrel if the oil is ready to be run.
The two blue ones are the holding barrels, the one red one is the final barrel. The valves allow me to fill or pull from any one barrel when needed.
The small red valve is used to allow filling of the final barrel when the WMO is filtered twice.
