Replaced tank assembly. Actually I think the supply hose was originally not fully seated in the tank and I think I could have re-seated it deeper through the gray bushing. When I set the line into the new tank, still leaking. Pulled out supply line and reset using a little more force and line went into the tank. Took the bushing clip off the other tank and used it for the supply line bushing. So far, no leaks. The thing to remember is to push the edges of each hose bushing inward to pull out the water lines. This was a little challenging. You have to really use some force to pull the lines.
