"91" Inline Heater Control Valve question?...
My "91" Vette's Inline Heater Control Valve is a Plastic Inline Hose Coupler like this Except, this is a control valve for a "92"-up Vette.
When searching for a "91" Vette Heater Control Valve online, the picture shows a Threaded Brass Coupler like this.
Does anyone know where this threaded brass heater control valve connects to, on my 91 Vette?
Thanks

Here's the location of the Heater Control Valve I temporarily replaced.
It's installed in the top hose underneath the Surge Tank.

Found it!...
The Brass Heater Control Valve threads into the front of the intake manifold. (It's called a One Direction Flow Valve).
By following the heater hoses, I found that the heater hose exiting the passenger side of the water pump connects to the top surge tank inlet (which also, has the plastic inline control valve installed), then the bottom surge tank outlet hose connects to the heater core inlet, then from the heater core outlet back to the front of the intake manifold, into the brass control valve.
So, it seems my "91" Vette uses Both the plastic and brass control valves...
