I am looking for a part or part number for a black plastic Tee fitting in the heater hose system. It has three 3/4 inch hoses attached to it and one branch has a restrictor disc in it. It is located in the engine compartment near the firewall. The only markings on it say "made in mexico." If I can get a part number, perhaps I can find one on Ebay or the Internet. I'm doubtful the dealer would be able to come up with one based on the age of the vehicle. Any help would be appreciated. I can't seem to get a picture to attach, but I'd be glad to send one to anyone who wants to leave me an email address. THANKS!
