Water temp thread size?

Anyone know the thread size for the stock water temp sensor (the one below the distributor)… I need to get a T in order to install my aftermarket 1/8 NPT sensor. TIA

If it’s like the oil sensor, and I’m betting it is, it’s not even an npt fitting. It’s a bspt. you may need an adapter.

Can anyone confirm that it is a 1/8" bspt thread size. if so, the solution is simple, http://tunertoys.zoovy.com/product/OTODK/Oil_Take_Off__Dual_Outlet.html .
