Ever since I installed this 255 LPH Holley fuel pump, there has been this wicked sounding high pitched whine coming from my gas tank. At first it was a little annoying, but now its starting to grow on me, and I wonder if anyone would mistake the pump whine for a supercharger whine

 

I had that noise with my first Holley pump. I thought it was odd so I called them and they said it would be a little louder cause it was bigger than stock. Two weeks later it quit. JEGS gave me a new one but it was another 5 hour job to change it.
