I have an 01. 5 that I bought new. I have been buying Fleetguard oil and fuel filters from cummins NW. Recently I ordered a filter maintenance kit from Geno's. I went to install the fuel filter and found that it is different than the one I pulled out. The one I took out has a hole in the top for the protusion on the under side of the lid to fit into, the one from Geno's is flat on top with no hole. I went to my local Dodge dealer and bought the "right" filter for the truck, it's the same filter as the one I got from Geno's. When I tried to instlall it I couldn't get the lid threads started, the filter seems to be holding it up too high. Am I missing something obvious here? Wouldn't be the first time!
