Thanks for the response. I will check the hoses but before I removed the old regulator in anticipation for the new one coming in I made sure water pump was building pressure. I did check all the hoses and fittings for wear and leaks. Question though. I would I check to see if the fluid is moving through the hoses when running. I know there was fluid moving as fluid was present in regulator after I had drained and refilled coolant.
