Here is the parts page for the oil pressure sending unit for my rig, not sure if yours is the same, show this to the cummins shop and they can confirm.

Not sure of the difference but both seem to be readily available.
You can also querry the REV parts website using the Monaco number but will pay a premium for them from them. I just think they don't want to fool with the older Monaco brands.

Another good source for this type of thing might be Veurinks, they use to sell Monaco's and kind of specialize in parts for them. Give them a call, they were able to get me a part and drop ship it to a location from me. Really good service. Even if a part isn't listed on their website they will be able to look it up as I think they have access to the old Monaco parts lists similar what I posted.
