95 cummins with B100?
 

For a 1995 cummins are there any fuel system components that will need replaced before using biodiesel? I'm sure this is answered somewhere but I didn't find it in the searches that I did.

Fuel lines? O-rings? Seals? Or should they all be synthetic and be ok?

Try posting your question in the Alternative Fuels section and you will probably get more responses :tu:
