I’m replacing an old temperature gauge with a new one, and I am using a Vintage Precision water neck so that I can have a thermostat closer to the engine head. However, this connection is going to leak. The brass adapter snugs into the water neck base fine, but the temperature gauge nut that “pins” the temperature probe to the adapter in the water neck bottoms out before the probe is sealed to the brass adapter.
I can spin the probe by its aluminum end after the temperature gauge nut is fully tightened.
How can I get around this issue?
