Strange beeping/whining sounds from electric fuel pump

Lately I've been hearing beeping or whining sounds from my electric fuel pump after driving a few miles and since the motor and exhaust produces a lot of noise I can only hear these sounds only during stops. It sounds like a home fire alarm that is mounted on the ceiling. I'm almost positive it's the pump. Anybody had this experience and if so, is the pump going bad? Thanks in advance to anyone that can give me a remedy.

Check connections for allowing air into the pump.
Install filter before the pump to eliminate foreign materials being pulled into the pump.

Thanks for the advice sir...but I did check the connections and they're all good and the Fram filter is located less than 3 feet from the pump. The pump is an Aeromotive brand and it is super loud and so annoying during idle. I'm going to replace it with a Holley HP 150 and hopefully I don't hear those beeps again. Thanks again.

Mount rubber isolators to the car, then mount the pump to the isolators. Never bolt an electric fuel pump directly to a metal part of the car. I used to use those black rubber muffler hangers that had holes drilled in them. Got them at Pep Boys, but don't know if you can still find them there. Maybe at a muffler shop. Also, don't attach a hard line directly to the pump. Attach short pieces of non-metallic hose to the pump inlet and outlet, then attach the hard lines to the non-metallic hose. With the pump isolated from the car in this manner, she'll be as quiet as a church mouse.

Thanks, I'll follow each of your steps to the T. I just purchased the rubber garage door seal which is thin and should wrap around the pump before securing it with the clamp.

I found a link to the stuff I was talking about. Use the clamp around the pump, with or without your garage door insulation, but mount the pump/clamp to the car using rubber like this......

No hard part of the pump or clamp should be in contact with any hard part of the car.

Thanks, I also found it on amazon where I usually purchase parts due to free shipping on most parts I order.
