I was talking to a rep at a biodiesel seminar and we were discussing the pros and cons of biodiesel. He told me i would have to eliminate any rubber lines that were on my truck (2005.5 5.9) because the biodiesel would deteriorate them. I was hoping someone around here has ran bio through a later model truck and knows what will happen. Can someone tell me what lines ill need to replace, and any other parts ill have to change? Has anyone ran straight bio through an 05 or later truck? What do i need to do to my truck for it to safely run on biodiesel. Thanks in advance for any help.
