I have been thinking of going over to
biodiesel now that I found a supplyer in my area but I have heard that the bio is not good for any of the
seals in a engin and will cause leaks. I am not to worried about the
fuel system because any leaks would be an easy fix but what about the injector orings on a 7.3 di motor?
I would consider replacing injector orings to be a lot of work. What about the fuel pump?
