05 fuel pump

i have an 05 century and have had the fuel pump replaced as it was giving a buzzing/humming noise under the driver feet. when i traced it back it was the fuel pump noise that was following the fuel lines up to the engine compartment. the dealer replaced the pump and the noise was gone for about 4 weeks. now the new pump does the same thing. anyone run across this issue and was the problem the pump or something else? thanks!

Did you change the fuel filter when you changed the pump?

yes i did. thanks,

It would be best to do a visual inspection of the lines to see if they are still in the frame brackets and not loose where they could hit the underside of the car.
