Since you said the first half has positive pressure and the second half has negative pressure Im guessing the highest postive pressure is right at the the outlet of the pump and highest negative is at the intlet. I am also guessing the pressure gradually changes. So it slowely goes from full positive, to less positive, to 0 to less negative, to full negative in the loop.
I was already planning on using 1/2" ID 3/4" od or greater tubing on the inlet mostly because 3/8" just wouldnt fit..
how extreme is the change in negative pressure from the very tip of the inlet of the pump to 12" away of straight tubing?
