I got around to finishing up my adapter to screw into the oil pressure port to hold both the factory sender and the Defi. I used a SS fitting from McMaster and rethreaded it to BSP and tapped the ports to BSP. I wanted SS instead of the brass other places offer. I just want to make sure it doesn't break on me. After starting the car is is amazing just how useless the facotry guage is. The factory guage barely hit 60psi, while the DEfi showed 75psi. I guess it is true that the factory guage is just an idiot light. Now I just need to get my fuel pressure guage and get it hooke dup so all three of my gauges in my DIN slot are functional.
