I need help
 

Hey there everyone! I'm brand new to the site and to diesels. I recently came into possesion of an 85 F250 6.9 and I'd like to run biodiesel. I have read that I need to change the fuel lines to viton, but where do you buy them. I looked at the fuel lines and they've got some different fitting I've never seen before. After I get passed the fuel lines what other seals will I have to change? I'm over my head, but looking to learn. I am reading the Haynes diesel engine repair manuel to get familiar. Any suggestions will be greatly apprecated!!!! Thanks

You might want to bring this to the 6.9 forum, those guys got all the knowledge you're looking for.
