zerg... if your talking about that large / short hose, you'll have to pull the thermostat housing (peice on the left), and the other peice that holds the other temp sender (peice on the right). I think they're all 12mm nuts, you'll need to get the intake hose off, and its a lot easier with the throttle cables out of the way.
Take that peice into Napa or wherever and get any cheap peice that size. I don't remember what I bought, but it was the right diameter, and was like 3 bux, so it worked for me. I don't like the factory clamps either.. never have, I'd get 2 new heavy duty looking clamps. It makes installing the whole thing a little easier.
Might as well replace your thermostat too while your in there if its not too new.
