So, what's the problem with Buna-N (Nitrile)? It seems to hold up just fine with VO. (I've been using it over a year in my filtering, dewatering, and fuel supply with no hint of softening, cracking, or any other deterioration.) Has anyone tried it with biodiesel? If it truly is a problem, it must be the alcohol that's the problem.
