Thanks!!

I looked at the sender you mentioned, it's specified to be a 1/8"-NPT which is obviously much smaller that either the original ½"-NPT or the modified 3/8:-NPT.
It looks like all you will need is just a reducer bushing to make it function.
Is this it?

Yes sir, that’s it.
I currently have an adapter but thought maybe I could get it to reach in there deeper. I heard about you and what your doing from Captn Fab so wanted to see if you could help.

Thanks for reaching out. I understand about wanting to get the sender further into the coolant flow.
It may be possible to modify the adapter bushing in a way that would allow the sender to go in further.
Putting a counter bore in the bushing and tapping it deeper might get the result you're looking for, then again it may read correctly just as it is without any modification.
I would try it to see if you get the correct reading. The aftermarket gauge might be better than the factory one.
