Turbo Oil Feed Line

Hello,

This is the first ever topic started by me and i need some help i don’t have a set of tap and dyes to find out the size of the thread the Turbo Oil Feed Line coming out of the oil filter housing going to the turbo is.

I the size so i can buy a mocal temp sensor gauge adapter to fit my gauge sender in, this is the adapter i want to use unless anyone can tell me another way without a sandwich plate.

The gauge sender is 1/8npt senders for use with SPA gauge Oil Temp / Oil Pressure as you can see from the picture the pressure sensor is already fitted.
