The leak(s) appear to be coming from the IP pump where the hard lines connect into the pump.... however I'm not 100% sure. At the very least, the top of the pump is wet.
Anyway, is this a case where the delivery valve O-rings have perished?

Could be, but have you checked your fuel thermostat for leaks? The DV o rings don't generally leave a puddle, but the thermostat does.
