The Blue pump has been around forever, they are the at the bottom of the food chain. Some are good some fail within a week, I never had luck with them so i bought other brands. It is a dead head unit, so run a 3/8 line or a #6an and call it good. Get a fuel pressure gauge and mount it where you can see it. You should have 5 PSI minimum going through the top end floored. Fuel delivery is about volume not pressure. People think cranking up the pressure will give you more fuel. NOT. I have this HP-125 nice pump supports up to 700 hp so they claim. Has worked fine, lots of volume steady pressure.
