I went to change out the petcock valve today when I when to torque the valve it snapped off into the fuel tank. Does anybody know the tap size I need to chase the treads in the fuel tank ?

hopefully, you won't need that if an extractor can pull out the broken part of the petcock

threads are m10x1.0, but many sets use an npt1/8X27 for that
