ELEC. FUEL PUMP NOISE

I installed a holley electric fuel pump on my barracuda. I mounted it on the inside of the rt frame rail just behind the wheel well. It is very noisy. It feels like its vibrating the whole rt side. Is there any thing i can do to quite it down ? I have other electric fuel pumps to try if need be. Maybe they will be the same. The pump i have on it now is the blue holley pump.
