Yeah, The instructions I found on the Pro Tec site didn't match those. It shows one of the lines from the pump being split through a selonoid and then into the pipe.....I am assuming this is only if water injection is used. Right where the manifold bolts to the head pipe there is a threaded plug.....I am guessing that is where the water inlet would be after the selenoid?????
Does the outlet off the head go right out the bypass?? The instructions don't mention that at all.
