Elio Addict
Yup, I added an oil pressure gauge to my Kia Rio using a sandwich adapter. It screwed in between the oil filter and the motor and had a threaded hole to attach an oil pressure sensor. Only took a minute extra to install during an oil change and never had problems with leaks, but it was something I kept an eye on since it was one more place where leaks/failure could develop. I would not do it again. I would tap into the block next time if there is not already a fitting.
