This TSB applies to 2009 Ram Truck DH and D1 vehicles (Ram 2500/3500 pickup and 3500/4500 Can Chassis) equipped with the Cummins 6.7L diesel engine, built after Dec. 15, 2008, and to all 2009 DC and DM vehicles equipped with the Cummins 6.7L diesel engine.
The fuel filter supplied as original equipment is now of a new design. The new style filter incorporates a dual element filter with a reusable shell. When replacing the fuel filter, rinse the shell with clean fuel. DO NOT fill the shell with fuel prior to installation. Follow the instructions provided with the replacement filter.
Replacing the filter does not require replacing the filter shell. During routine maintenance, use P/N 68061634AA (filter element only). If damage to the shell occurs during service, use P/N 68061633AA (fuel filter element and shell).
