I have had blue holley, and a edelbrock, both were noisy. I have a 20 gallon cell with 8an fittings. I was thinking of using braided 1/2 inch line, but see the largest I can use is 7/16 I. D. Anyway wondering what pump to go with I will be using a demon 1000 something carb, 150 - 250 shot and will be running a return setup. Does anyone make a pump that will satisfy the need and not so loud?
