Not really interested in running an electric pump but I think it probably would help. Although not identical in the set up I have 4 or 5 that run carbs and mechanical pumps without issue and I have run them for years down here. I guess I really cant say what it aint til I can say what it is though. I thinking more and more it's the minimal space between the carb and the cast iron intake, many of the others are aluminum intakes, one other Edelbrock but it's on aluminum. I hate this time of an issue when I have something to try and have to wait til morning to get parts and tinker.
