Water Pump Inlet Pipe for '89 1.6L

[JJR]

Does anyone know where I can get a replacement for my leaking Water Pump Inlet Pipe for an '89 Integra 1.6L? This is a horizontal metal pipe about 13 - 14" long conecting the water pump and thermostat housing. It has O-rings at both ends and several smaller inlets/outlets along its length. It is sometimes referred to by other names but this part name is on the ALLDATA exploded parts diagram for the cooling system.

I have tried many new and used parts suppliers with no luck.

Also, does anyone know what other years. models, etc of Honda or Integra that would have an identical pipe?

Thanks everyone.
