I have a 2003 Dodge 3500 with a cummins diesel 5.9 engine. It runs fine when the engine is cold, but after it warms up it lugs down. This is the first diesel engine I have had any dealings with. I was told that it has a fuel filter and that it needs changing. Is this something I can do and if so where is it located? I have opened the drain on the Fuel/Water Separator Filter, but that didn't help any. Or is it possible the Dampner is not opening up after the engine is warmed up?
