I know what you mean about the Holley pumps being noisy, had a couple of customers who used them. On the pumps I use I used to stuff rubber grommets in the mounting holes, but found that really didn't make any difference. Mounting location does seem to make a difference, mounting to a frame rail works but mounding to an inner fender or or trunk floor gets a little noisier.

Normally is possible I like a mechanical pump best, and just add the electric pump to fill the carb on startup.

I tried rubber isolators between the frame and pump, but it made little difference. I don't mind spinning the motor over to refill the carb(s), it allows time to build oil pressure, jmho..
