Answers :

YOU ARE GOING TO NEED TO REPLACE THE FUEL PUMP, THE PUMP IS WORN OUT, THAT IS WHY THE NOISE, THE FUEL TANK MUST BE PULLED TO DO THIS, I AM A FORD DEALER TECH WITH 20 YEARS OF SHOP TIME AS A FORD MASTER TECHNICIAN.
Hi...

Pull the engine accessory drive belt off and check the pulley\015\012bearing and the nose of the water pump and AC compressor for play, this\015\012may be the AC compressor pulley bearing or the water pump pulley bearing

Good luck
