I just clamped off the two hoses connected to the pump and removed the cover. Cover seems fine. Rubber ring seems fine. There isn’t a gasket though...
I put a small amount of permatex gasket maker around inside edge of the plate and put it back on. I removed the clamps and it’s still dripping..
Here’s a video from underneath showing the leak and below is a wider picture:

The drip seems to be forming from further back on the pump, rather then the pump plate. Any thought/tips appreciated!
