Get it out of there and replace it before it develops a leak that may pump fuel into the oil pan and do a autopsy later!!!

I have had just terrible service from ALL Airtex fuel pumps. Don't see many mechanical fuel pumps nowdays, but the 2 I installed both had issues. One was noisy like yours, the other leaked at the major crimp where they are put together. It was a Chevy model. Their electric fuel pumps are total trash. Noisy, pulsating fuel flow, low pressure, low volume, high failure. We were seeing about a 50% failure rate in 6 months of service. I will not use them , period. A free replacement does little good when dealing with a full 34 gallon tank on say a Suburban. ACDelco or Delphi are consistently good fuel pumps, mechanical or electrical.

I've got about 60,000 miles on my airtex(large canister) mechanical pump......No issues. As a matter of fact RobbMc recommended it since I have a stock engine. He could have sold me one of his but said the airtex would do....

That thing honk that loud when it's pumping fuel?
Does capping off inlet or outlet change it's tune?

The honkin' dry sounds close to normal to me. Stronger pumps are louder when pumping dry like that. But it should quieten down when it's wet and building pressure.
