No problem man. Glad I could help you out. Just fix the oil return line and take it for a drive.

To hook up your guage, you need to either replace the stock oil pressure sensor or use brass fittings to create another hole that you can screw the sensor into. The first idea sucks because your idiot light on the dash will be constantly on, so I would go to Home Depot and pick up some fittings to tee it off with.
