What Do I Need To Do?
 

I have a 1996 F-250 4x4 PSD. I have been making BD with a friend for several months, but have not had my truck on the road during this time. The reason the truck has been in the driveway is that it has a fuel leak. I already know that I am going to have to tear into the fuel system and I am wondering what seals, lines, etc. I can replace with parts that will be resistant to Biodiesel. I have gotten some great advice from this forum in the past and am hoping the experts can come through again!
Thanks a lot,

Just fix the fuel leak. All fuel system parts are 100% compatible with Biodiesel.

What year did they start using compatible materials? It has to be synthetic rubber e.g. Viton, right? What do you know about the injector o-rings?
Thanks a lot,

93 or 94. I don't know what the O rings are made out of.
