If I were you and this was just a temporary fix for a leaky heater core or something I would just take one of the hoses to the local parts store and just ask for a generic u shaped hose. They should be able to find you what you need.
If this is a permanent thing, I would take off the heater pipe on the lower intake, get an adapter to put the ECT in the hole in the intake, and plug the port on the water pump.
