The "high" pitched whine in my MKX doesn't seem as noticable now, after a 18 months. Either its quieter or I have grown used to it. The noise is/was most noticable when idling, since there's no road noise to cover it. A Ford master mechanic friend advised me relatively quickly that its the fuel pump and there's no guarantee that a replacement wouldn't do the same thing. Since it is no long as noticable to me, I've let it go.

I'll be interested in whether the replacement fixes the high-pitch whine. I have a new MKX with the same type of noise that is already driving me nuts. Please post the results of the replacement.
