I have decided to purchase a Di Pricol oil pressure gauge to match my boost and EGT gauges. I know there is a plug in the top of the oil filter housing but I was wondering if anyone could give me some pointers on drilling and tapping the plug so I don't mess up the install.
I know some of y'all have done this so any assistance would be appreciated.
Thanks,
