I don't run Biodiesel though, the person before the guy I bought the truck from ran biodeisel in the truck, I run a WVO blend in the truck.

Edit:

Ran the truck for a few miles down the HWY, back and forth (keep the truck close to home in case of problems) no problems on the blend, the bypass on the 2micron filter works great, ran the last couple miles on diesel to clear the lines.
