On the registration plate for my pump I have "TP-103" stamped on it. Anyone know what this means, it looks like it was added later. So, my best guess would be that it is the mark of the pump shop that did the work to my pump, but I don't know what shop did the work. Does anyone recognize these markings? I know a lot of you guys are performance pump shops, so I will eventually figure it out. Thank you.
Here is a picture of the plate. Thanks.
