I work at a biodiesel plant and run 100% in my 84 TD and my 95 dodge cummins

After the 3rd tank. I canged both filters. I have been running B-100 for about a year now. The only problem so far I had is a return line pop off an enjector on the Merc but it was 27 years old. Replaced it with new but the same fabric coated lines. From what I have herd the fabric coated lines are bio friendly
