Grundfos Pump. ?? Water

Plumbing is a persistent problem for me. As I was changing filters and preparing to depart for the Prevost Show, I noticed water coming from under the pump housing. Every connection is water tight and no visible sign of water except coming around the base. I have attempted to attach a picture of the issue. I would appreciate any insight.

When not using the faucets toilet or shower do you hear the pump cycle? This would tell us what side of the pump the leak is on.
