The Medcine Man
I have asked a question similar to this on here before but let me just get to it. I was told by reputiable engine shop to run drain backs off the heads. I have 3 stage dry dump system do I need to tap and drill the pan and run the drain backs? I also will be running vac pump up top also do I need to run separate drain backs or can I run a Y block then into one. Final question drill and tap up high as possible on the pan or can I run it to an un used fitting at the bottom, plus run 12 an top to bottom???
