I have a 94 Z28 and my hoses are going bad. One of them has a bad slit in it so I'm going to replace all of them.. The only thing is some of them have metal couplins on them, are these special order. The one with the bad slit on it is the one on the bottom left side of the water pump and it wraps back towards the firewall. I really need it replaced but I don't know if I can get the hose at an auto parts store and how hard it is to change.

 

Also how do you get the couplins off?
