New Fuel Pump Worse Then Old One!

[MD Ever]

So my fuel pump was singing. Time to replace it right? I ordered a new pump from RCM and put it in last weekend and the new pump is louder then the old one. This one doesn't sing, it's more of a buzz/hiss sound. The thing almost sounds like an air compressor tank draining. Anyone else run into this with a new pump? In my career I've installed many fuel pumps and never heard a new one sound this bad. Did I do something wrong or did I just get a bad pump? Thanks.

P.S. It was just a standard Carter/Federal Mogul pump.

Some just are louder than others. Generally the more gas in the tank the quieter, but even with a full tank in my '97 the 255lph pump could be heard pretty well.

my pump is darn loud... but that might be becuase there is no sound deadening or carpet...


but yeah, a good pump should make a loud whine/ buzz noise

I prefer the noise, then I know its on. I just did my FP over the weekend and can not hear it AT ALL. Kinda makes it tough to tell if it ever goes out without a FP gauge.
