After that watch your injector return lines. The MB rubber does not seem to do well with biodiesel. Maybe their new lines handle it, maybe they don't. I sell viton lines the absolutely do handle biodiesel and they are cheaper then the overpriced MB lines, IMHO.

I also sell o-rings for the rest of the fuel system. I figure them out as people ask. If your engine is not one that I have figured out, let me know and I can work on finding the right ones for your system.
