I agree with Hab, that bus IP brobably died because of bad fuel/filtering/Lord knows what. After the research I've done, I damned sure don't think it was a lack of lubricity on the part of biodiesel. Additionally, the facts are mighty thin when it comes down to what caused that pump failure, the age of the pump and what the fuel source really was.

FWIW, home brewed biodiesel is problematic at best. It takes a lot more effort than the so called "biodiesel kit" manufacturers let on to produce consistent, high quality b-100. However, even ASTM fuel (bio or dino) can be nasty since ASTM certification is only required on an annual basis.
