What could be a high pitched sound coming from the fuel tank?

My 2001 Chevrolet 1500 Suburban has a high pitched sound, almost a ringing, coming from the fuel tank area. DO you have any suggestions as to what the cause of this may be?

Re: What could be a high pitched sound coming from the fuel tank?

The only thing that can cause this condition inside the fuel tank would be the fuel pump. Have a certified mechanic inspect the noise condition to see if a repair would be needed.

I don't know if you are the original owner but there is a fuel module modification that is a recall. Have the dealership check service records to see if your vehicle was repaired in the past for this condition.
