My old Holley blue was mounted in the rear of my boat (not my doing) and my tank is in the bow. (it burnt out). I bought a new red pump and mounted it by the tank. I got rid of my pressure regulator because the red is internally regulated to 7psi. Basically after replacing the blue with the red I lost fuel pressure. At idle I was pushing 6 psi, when I got on it, it would slowly drop down to 2 psi at WOT. I have a 454 bbc, 850 demon carb. None of my fuel lines are kinked, and my filter is clean. Should I go back with a "blue" and a regulator? Or is there any specific reason why the red isn't working? Any Ideas?
