Hey TSAN - Just enter the cassette potty manf number into GOGGLE followed by the word 'MANUAL' and you should find a part number that way.
I haven't looked yet but my RT14 probably came with the cassette potty manual in my manual package. It has a whole bunch of installed appliances manuals included.
If they want bunches of monies for that part I would go to WALMART and pick up a 12VDC boat pump. They don't cost all that much as the capacity is very low. Shouldnt be hard to retrofit any 12VDC small capacity pump to your pottie flush switch.
This is for your RT13 right...
