The FS-2500 bypass filtration system was installed on our ’05 Dodge Ram with the 5.9L Cummins in only a few minutes. You can see exactly how the heavy-duty filter bracket easily bolts to the engine. The filter head then bolts to the bracket. This ¾-inch filter bolt in the center of the housing keeps the filter bowl attached. Stainless steel lines are an option we decided to go with. The oil pressure “IN” line is routed from the factory oil filter housing (first remove the plug) to the new bypass filter head.
