Thanks for the info and the links secluff (putting P/Ns in book), this was my grandmothers 50k original 73 vert so nobody has messed with it.Hello Bryan,
The original heater hose elbow for your car is D3OZ-18599-B. (The D3OZ-A or B will interchange) That one has the provision for a PVS valve. The PVS valve is a temperature-controlled vacuum valve used to control the vacuum from your carburetor EGR port to the EGR valve. It's intended function was to aid in warm-up driveability. To see that it's still on your car is amazing since a lot of 'em were tossed when "Cleaning Up" under the hood back in the day.
If your car is running fine with the present system you may want to keep everything as is. The D3OZ elbow can be a little harder and more expensive to find over the elbow without the valve provision. There are a couple on E-Bay https://www.ebay.com/itm/NOS-1973-1979-FORD-GRAN-TORINO-RANCHERO-ELITE-351-2V-HEATER-WATER-ELBOW-FITTIN/254604599581?epid=1723925175 and a Google search shows a few but this one stuck out because of the price. https://www.bphimheo.com/index.php?main_page=product_info&products_id=688177 (I have never dealt with this company)
If you feel like you want to do away with this system you can always use the elbow Canted 393 found.
Good luck with your project.
