SENDING UNIT THREAD SIZE ???

[MIDNIGHT RIDER]

Does anyone know the thread size of the factory gauge fittings where they screw into the engine??

I need to know size for oil-pressure and water-temperature at the factory locations.

Engine is 1985 6.9 International.

They are pipe thread. Usually 1/4" NPT.

Oil pressure is 1/8 inch pipe. Depends on where you are putting the water sender, as there are multiple stock locations. Mine are 1/4 inch pipe in one location (front of driver side head) and 3/8 inch in another.

Hope that helps.
