Careful with those fuel lines.... And carry extra filters.
excerpt:
Besides better emissions, research has indicated an increase in engine longevity, a decrease in engine maintenance, and a better performing engine. Because biodiesel has solvent properties by nature, it acts as a cleaning agent on the fuel system in diesel engines. This means that it cleans things up the more it's used.
Because of these solvent properties, some have noted that fuel lines in older diesel engines may degrade because the biodiesel breaks them down. Particularly susceptible are fuel lines made from natural rubber. Most of the susceptible fuel lines can easily be replaced with inexpensive fuel line that are biodiesel compatible. If in doubt, check with your local dealer. The lines usually degrade over time and develop small seeping leaks instead of large leaks.
Diesel engines made after 1993 and sold in the United States typically won't have this problem as the fuel lines are already biodiesel compatible. This is because of a reduction in sulphur in diesel fuel in 1993 in the United States that necessitated manufacturer's needing to change the fuel lines with non-rubber lines.
