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.
