I'm pretty sure there is both the intake and return line. It has a soft W clamp that bolts to the back of the head. Going off memory they both are very short to the hard line and then back to rubber as it goes down into a shield along the tranny. IF you get the bolt out of the head replacing the hose will be a royal pain with the intake on. BE SURE TO RE-INSTALL THE BOLT or the hose will crack soon and leak again. I just up loaded pictures of it in my gallery..
