I am going to make a fuel blender and I already have a dual-filter setup I can use. If I want to filter a mix of diesel and WMO should I use an oil filter or a fuel filter or 1 of each?

 

I used an oil filter going in and a fuel filter going out.
After you have mixed the fuel and oil it will be a lot thinner and go through the fuel filter easier.

From what read over time , do not use any paper, cardboard , celouse filters , the reasoning is that the moisture / water makes the paper swell and when that happens its like closing a valve .
So that gets you to polymer fiber , then its a mater of micron size and brand.

 

So which brand filter uses polymer fiber?
