Just don't want the OP to think a Magnafuel pump is quiet. I don't hear mine either when the car is running with open headers, but throw on some quiet exhaust, and it's a different story.
The Mallory 140 pump with a return regulator, is about the quietest elctric setup you will find. It's just a matter if it can keep up. My guess is with your current combo, yes it will.
