I did it last summer. You need to first cut the old hose off so you have a little more room. Next you need to very carefully cut off about 1/4 inch of the pipe on the waterpump. You have to go slow, there's not much room. Be very careful not to cut into the intake manifold as others have done. With this little section of the waterpump pipe gone you can slip the new hose into place, and there's still enough pipe on the water pump to clamp it in place. I wound up replacing the water pump about 6 months later when it went bad, so I'm back to a factory configuration now.
