220D vac pump interchange question.

Will a newer-style single line vacuum pump (OM 616, to be exact) work on an old 220D motor by simply plugging the intake manifod port? It appears that the bolt circle is the same where it mounts. I realize it's not "original", but will it function correctly?

Trying to perform a "cheap" experiment with what's laying around the shop...

Thanks...
