I am having a hard time finding the Cummins or Dodge part numbers for the O rings that seal the oil feed flex line to the turbo and at the other end to the oil filter adapter. The O rings go onto the steel fittings that the oil line screws on to. I also need the part number for the O ring that is on the steel fitting that screws into the turbo main body. That O ring seals the fitting to the turbo main body. I am going to call Cummins Pacific if I can get the part numbers. Thanks.
