You'll need to get in touch with member MikeR as he makes a fitting for the front engine cover to convert it to 1/8th" NPT which is what the pressure transducer will 99% probably be. As for water temp, post what make/model gauge you are using as you may be able to use the stock sensor. If that's not the case, and you're handy with a wrench, you can tap and thread the water pump and put the fitting in there providing it's not to big. There is a nice flat little spot on the top of the waterpump that will work perfect for this if the sender is less than 3/4" in diameter and shorter than 1-1/4" after the threads. Most will fit in this area but there are a few that are bigger than that so just giving you a heads up.

Good luck with the setup and I'm anxious to see pictures.
