I’m using an Edelbrock also and was in on a discussion this past weekend with some others who are running the same. They have had good results putting in a fuel pressure regulator. It seems that the Edelbrock likes the pressure down around 5 lbs and most of the new pumps put out somewhere between 9 and 14 lbs. I did go the Edelbrock web site and they mention to use the lower pressure. I haven’t tried it yet but you may want to keep your ears open for that. In looking up pressure regulators there seem to be a wide variety but also a wide price range.
