Thanks Bobby I read a post from way back from Lynn E. Hanover whom I understood was well worth listening too. He didn’t mention any need for the hole between inlet and outlet. He did however talk about making sure the outlet was restricted compared to the inlet to prevent pump cavitation. He mentioned that he uses a 5/8” restriction, however that all systems are different and depend upon rad resistance and plumbing etc. I’ll experiment a little and see what happens.
