Looks good to me, I would use #10 between filter and pump. I ran a very similar set up for many years, went 9.60s with it in a 3400 lb car. People don't understand that it is designed to keep 7 lbs of pressure in front of regulator.(or whatever you set it to) It won't see high pressure like they think. It was the most steady pressure system I ever had on my car.
