So what's new for 2009 for our beloved Cummins other then the updated fuel filter?
Cummins 6.7L Revised Fuel Filter
Well the first thing that was pointed out was that the Turbo now has an access port on the Turbochargers exhaust housing for cleaning. They also revised the water inlet housing and alternator bracket to accommodate new flexible braided coolant lines with O-ring fittings that go to cool the exhaust gas recirculation heat exchanger. Other then that it looked the same to me.
