Dripping MMI Pedestal Pump

I have a newish (maybe 2-3 year old) MMI Pedestal water pump on my late model A4.

No matter what I do I am getting a steady water drip from the lower thumbscrew area. I've felt around the pump and hoses and it's definitely coming from the lower place on the pump.

I've cleaned it up thoroughly and replaced the oring. Still dripped. Gave up on the oring, and tried copper RTV which usually seals about anything, but it's still leaking.

The oring is stupidly tiny. Is there a paper seal available as well? Better backplate? I'm sort of at a loss to get this fixed right now.

Thanks,
Jack
