Yes, you have a leak somewhere between your water pump and your sink. So you know that it is on the outlet side of your pump, and not the inlet. You have already removed some of the plumbing lines from you investigation.
Here's how I look for leaks:
Shut off the pump.
Mop and towel up ALL moisture in the leak areas. Get these areas absolutely dry.
Be able to get visual access to all of the plumbing lines between the water pump and the sink, if that's where you have localized the leak to.
Turn back on the water pump and watch immediately. If the switch and the pump are widely separated have a helper turn it on while you look. A mirror and flashlight are big helpers when looking behind or under cabinets.
You should be able to find the leak quickly this way.
Once you do, repair the spot with the appropriate material.
After you have finished the repair, dry everything off again, and do the check over. Compression fittings have a way of needing another twist before they stop dripping.
I hope this helps, ask more if you need more.
