Engine Water Temp & Oil Pressure Sending Unit Sizes

[markinms]

1990 5.0L engine.

I'm installing custom gauges from Speedhut and the sending units for both the water temp and oil pressure come as 1/8" NTP. This is too small for what I have and will require an adapter to work.

Does anyone know the size of the oil pressure sending unit and the water temperature sending unit that's installed on the thermostat housing?

Thanks for any help!

I’m new here and doing the same project. Any luck figuring out what thread size these things are? Maybe metric...
