Quote: Best thing I ever did for my Holley Blue Pumps was ditch the dead headed regulators and go with a Moroso return style The pumps are a whole lot quieter and seem to last longer set up as a free flow system.
Same here with ONE blue pump and fuel log. My tank (2 gallon) was in the front, 800+hp with a 7320 carb, ran 5.50-125 eight with loose converter( took em 4 tries to get it tight enough) did not run lean. I would think most pump problems traces back to lines from the back being to big, hard to overcome gravity with that much fuel weight.
