I actually meant to ask Cummins last time I bought filters.
Call a dealer and ask if he has or can get you a Fumoto..
If not,ask him for a replacement plug size so you can order one on-line.
Or the Fumoto site/ help desk may have the answer.
Get the one with the hose fitting and just keep an old gallon oil jug from the previous change for the old oil and just drop it off at the service bay for disposal or invest thousands for an oil heater for the winter months!
