I don't know if it is normal or not, but if I pull my lines off at the pump while under pressure, some water spray will shoot out the pipes from the back pressure.
A larger pipe will actually likely have more of a problem with water gathering in low places than a smaller one because the velocity of air travel within the line will be much slower at the same CFM for the larger pipe.
I don't know if it is really a problem as long as it is not freezing weather. In freezing weather the line could freeze shut. But otherwise I would think the gurgling would only create a minimal resistance to the air flow. But I don't really know that for sure.
