Making biodiesel for 6.7 powerstroke

there is no station close enough to me to make it worth getting B20 so I wanted to plan on making it myself. I didnít want to push it or anything on how much %, b20 is fine with me and I know itís rated for that in my 6.7. I just wanted to know if someone could explain the washing of it a bit more? Specifically wet washing as I fill one every other week 30~ gal so the time of settling isnít an issue but I just wanted to make sure you add water at about a 1-1 ratio and mix it and kettle it settle? Is that really it? And it will go through atleast 2 fuel water seperated filters before entering my tank to be safe

if the water emulsifies...the water separator will not trap will appear as a Vaseline looking substance on you filters..eventually clogging them.

No offense, but not even close.

Settling alone will never be enough to dry biodiesel. It can look crystal clear, but can contain dissolved water. In fact, since biodiesel is hygroscopic, properly dried biodiesel can absorb enough moisture from the atmosphere to potentially cause problems down the line. You need to be below 500ppm moisture.

I have been water washing for over 10 years and use a combination of bubbling and modified pump washing. It works for me, my fuel is great, and I currently have no desire to move to any form of dry washing. I would estimate with each 40 gallon batch, I use around 30-40 gallons of water over the course of the wash process. Then I test for soap content before proceeding to the drying process.
I use a heated spray dry process and utilize the WHW method of testing moisture content to below 500ppm.

Here's a couple links you might want to look over before proceeding:
