2003 Mazda tribute high pitch noise coming from fuel tank area?

The noise is coming from the fuel pump , Mine got louder until I got fed up of it so changed it for a new one not cheap but worth it for some peace and quiet. It might of kept going for longer but it was about to fail so instead of getting stuck somewhere It was changed. The pump was causing a few problems hard to start and a bit hesitant as its electric the bearings were causing the noise and you can't lubricate it. Shame there not cheaper to buy??
