There's an additional concern too - the Holley Blue needs a pressure regulator, since it's output pressure is in the 14 psi area. The reg they supply is a total POS, by the way - It really needs a return-type regulator and a line back to the tank.

You may also wish to know that the quality control in the Blue pumps has slipped over the last few years - I currently have one back at Holley to find out why the pressure goes to 3 psi when the pump gets hot.
