Temp Gauge Sending Unit Location on Edelbrock SP2P-318 Intake?

Ok I figured it out.
Went down to Home Depot and got some adapters in the plumbing pipe section.

Noticed it takes awhile for it to register temperature though?
But it does seem to work.

What is normal operating temperature on a 318?

Heres a couple pics.
What is that adapter called cause I need one also?
