Hey guys! First post here. My whisperflo pump has a slow leak from the bottom. I opened up the strainer and there Is a small black gap. Is that supposed to be there?Black gap supposed to be there?

The gap does seem odd, however, may not be the cause of the leak if you're unable to locate an external crack or gap in the housing. You will need to inspect the pump closer around the seams.

So I removed the pump and replaced the big shaft seal and the smaller circular one. Lubed everything up, tightened it nice and tight and the leak seems worse the before?
