Buy another one, sounds like she's gonna blow! I have only experienced a noisy fuel pump on my kids VW cabriolet. It's common for those models to squeal before they fail.

Chevy truck fuel pumps are notorious for failing I have a 2000 siverado and am about to put #4 in it. I'm doing this one myself because I'm tired of paying 900 bucks a pop for a shop to do it. I'm 6 yes old and have only owned two GM products. A GMC Yukon and this siverado. Never in my life have I had to change a fuel pump on anything but GM. I'm buying after market pump this time.
