So I want to fit a water temperature gauge and want to fit it in the spare port in the thermostat housing. I know zep racing sell an adapter but it’s expensive for what is is when shipping is take into account. I did some searching and found someone posting that it was M16 x 1.5 it’s definitely not a metric thread as I have a metric thread pitch gauge here.
I believe it’s 3/8 Npt but before I order a fitting can anyone confirm?
