Hey, I'm in the process of changing from the old style manifold to a new 2, I have everything hooked up however I was looking at the service manual for the 4.3 and It showed a two piece system with the water inlet from the pump on the riser instead of on the bottom like my old one, I was wandering if anyone had changed over to the 2 and if so did you leave the water inlet hooked up on the bottom or move it to the riser?? I just dont want to hook it up wrong and then get water somewere it doesn't belong. Tks for the help
