Drilling for map sensor barb
I am going to be drilling a hole for the fitting to supply vacuum to my map sensor on my tpi plenum. Do I have to use a special tap or anything for a 1/4npt fitting?

I thought that was the factory size. I bought used original ones and the seller listed them as 1/4 npt.
