Biodiesel is eating the fuel supply hose from my tank!

For those who use biodiesel, what have you done about replacing the short length of hose that comes out of the fuel tank? It has a fitting on one end that screws into the fuel strainer, and the replacement part from Mercedes is not biodiesel compatible. I believe that my hose is getting eaten from the inside out as evidenced by constant clogging of my prefilter with black specks that I do not think are fungus.

Does anyone know what thread size and pitch the fuel tank strainer has on the bottom where the fuel supply hose screws in? I may need to reduce and convert this down to 1/8" NPT so I can put a hose barb on it.
