so your tryin to hook up your oil temp gauge? there are two spots for oil. one up by the intake tube, and the other is on the bottom down passenger side.
i believe some members on here have used the bottom port for pressure. i remember reading a thread about oil pressure, and people were talking about using those two different ports. dont quote me on the port being there. i have never really checked myself. its prolly going to be a 3/8. so you will need to get a reducer down to 1/4 inch.
