If dino diesel (regular diesel) was used for extended periods of time before you switched to bio, then carbon deposits build up in the fuel lines. Biodiesel acts like a solvent and cleans your lines out.
In general, it is recommended to run a blend to overcome issues of rubber degradation. The main thing is probably to make sure your biodiesel is free of water. Depending on the washing process, if water is still in the biodiesel I have heard of bad things happenning if running B100 that has water in it. Lot's of people have run B100 without issues though ... probably lot's more folks on this board that have more/better input than I do on this.

I took the line off to the prefilter and pressurized the fuel tank getting about 3 gallons out that had small black balls in it. I replaced both fuel filters and noticed today a week later that the primary filter is clogging again.
Has anyone else on Bio-diesel had this problem and what did you do?
Thanks for the help!
