Yep, the thermal gun gave me a false sense of security other than the one spot on the front of the intake, the mechanical gauge was right on the whole time, as expected. The hard heater line fitting showed high temps but that was it. Even the water neck and hose were low.

I agree on the sender, the Fitech manual says to tape it, I didn't and it sealed. The first one was not taped either, it is just a bad sender, honestly it looks like a low cost copy of the OEM model it uses. I use a very small dab of thread sealant, just enough to fill any gap that might open up since it is aluminum and brass.

Thanks for the feedback, I learned something about the thermal gun.
