    Running a Stock SD33T with biodiesel---is it just a matter of changing a couple of rubber hoses, or is there some required "conversion kit" or something?

    What mpg can I expect?

    How is the engine performance?

    Hmmm...No replies all day. Maybe I should have posted this question on another forum?

    The SD33T or NA run fine on 100 percent biodiesel. When you first switch over, the biodiesel will dissolve years of crud in the tank so be prepared to change fuel filter a few times.
    After some months the biosiesel will soften the rubber fuel hose and it will need to be replaced with the 30R9 hose. The nylon fuel line should be fine.
    After that you should be good for years of running BD or petrolium.
    The new ultra low sulfer fuel is also hard on hose so everyone may have to do the hose upgrade even without switching to BD.
    Next when you are ready to run used vegetable oil post again!

    I have no idea what 30R9 hose is but I would use viton. That may be what 30R9 is, but it isn't cheap. I just changed the filter on a powerstroke for the first time running bd for 10K miles. This truck had 166K when I started using it. But you should be changing the filter every 20K at the least. I would also suggest adding a water separator to your stock fuel filter. Yes, you can still use the stock nylon line. Your mpg should be really close to what you're getting now, shouldn't have any noticeable drop. Change the hoses as soon as possible the bd will eat the natural rubber lines alive.
