Unique thing about the Cummins in the Dodge.... neglect to change the air filter.... the engine WILL get it's air, even if it has to fold the air filter down the middle and suck it halfway into the lid. Fuel system pretty much the same story.... neglect the change the filter, the cp3 pump WILL pull fuel through the filter, along with filter media and contaminates. There's a 15K service interval for a reason. Cummins/Fleetguard/Mopar filters all the way!
