where to hang my holley blue electric pump?

Hang it on Ebay, if you don't want to go deaf. And have it over-power the regulator. Or like my 2nd one, warranty; leak from the bottom, and dump 3 gallons from the cell to the shop floor overnight.

You my friend are correct. I tried everything to quite it down but it still buzzed like a airplane flying low. Unless it's a drag car with open headers then the Holley pump won't be a problem but something to drive around town, cruise it was awful. It's gone now.
