Should I have one of these for both the feed and return, or just on one side?

Typically one will do it.

Will this valve fit a 1948 to 1952 Ford 8BA V8?

You may have to get a fitting to adapt is all.

Is this fitting for 1/2” heater hose?

Willys Jeep Parts Tech:
Yes, 1/2 inch hose

How do I open this? I have it on my Jeep. Do I turn the nut then the wings or what? No fluid is running to my heater.

You just turn the wing nut to open and close the valve inside.
