Buna rubber for bio diesel

Is this the right type of rubber for biodiesel use? It advertises that it is acceptable for alchahol use.

New school of thought:
Viton not necessary. New OEM fuel hose will work just fine. It's not the rubber compound that makes original fuel hoses break down under biodiesel use. It's the fact that they're 20 years old, so the bio serves as the straw that broke the camel's back. Viton is way more expensive than regular- if you want to save a wad of cash, just buy new regular hose.

Viton is a non essential for running bio. Hose usualy start leaking because they were 20 years old to start with, not because they were rubber. I have never seen new rubber hoses leak on bio. Hmmm......
