    I recently bought 2 trucks from auction, both are 2009-2010 trucks, dpf but no def.
    Both trucks seem to have been sitting for a while, and on the dpf the hoses for the differential sensors are all cracked and ripped, is it possible to just replace the hose or do I need to replace the sensors as well as the metal tubes?

    You could likely just replace the hoses. Buuuut if they are cracked and ripped. Odds are VERY good moisture has gotten in there and caused rust and corrosion damage if its been sitting a long time. Emissions systems dont like that. I would just bite the bullet and replace everything otherwise odds are very high your going to have issues later. Granted you may not. But is a tow and angry customer, then having to do the job anyway later going to cost more then doing the job correctly now?
