Equus 8200 in a 73 Satellite

[r0yce]

In your pic (post #17); the OEM sensor on the bottom is designed to be installed directly into the water with (pipe) tapped opening. The sensor shown on top is designed to be installed into an adaptor (whether open or closed style) which screws into a (pipe) tapped opening beforehand. If the adaptor is a closed style, then the void should have a high temp grease like never-seize to displace the air between sensor and well (adapter).

How about a pic of your available possibilities in the manifold especially?

Thanks for the ideas!
Of course I forgot to make pics while working on it today.
I'll Post pics tomorrow when I'm at the garage again.

Don't buy before research, but it looks to me with my limited knowledge that this is going to be needed, unless you already have an adapter;

I also looked at that set but the smallest adapter they have is 1/4" NPT.
I'll have a look if I have a few more options on the intake or water pump.
If non, I'll go for an electric gauge which has the right 1/8" NPT sending unit

Here is what I used for that gauge. Go to jegs, type in mopar thermastat housing spacer and your answer will appear
