Well... I broke the water temperature sending unit when screwing it into the adapter. Probably tried to tighten it in too much and it snapped off inside the adapter. Now I need a new sending unit and 1/2 x 1/8 adapter. Anyone know if I could just pick up a water temp sending unit at a Napa or something like that or will I need to order one? I don't even know the part number. This would be from the GPS gauges with I think are from Speedhut.
