I have a 1996 S320. someone bypassed the whole duovalve-heater system. I need 2 hoses, one that goes from the water pump into the duovalve, and the other that goes from the firewall back into the engine. does anyone know what part numbers I need? Maybe a photo of what it is supposed to look like?

I looked on EPSnet, but I can not identify the correct hoses there-- the diagram is a bit confusing.

any help would be appreciated!

once I hook it back up, I'm afraid of finding a bad heater core or duovalve , but I guess there is only one way to find out!

thanks.
