Justin, I have been looking for one of those tapes for several years with no luck. When I found my sell-a-vision pump a few years ago I did a lot of research and came up empty. I am putting the finishing touches on the restoration on mine and have the tape mechanism and motor completely rebuilt with the exception of the tape. My brother is in the arts and graphics business and has an idea to reproduce a tape that we hope works about the same as the original ones. If and when we get one made I will post the results here on Oldgas in case anyone else with a pump is interested. Good luck on your search. If you discover more than one of the original tapes I would sure be interested in it!...GB
