Sounds at least like it's able to keep up with the demand. I don't know that I've ever paid any attention at all to my fuel pump. I certainly don't hear a squeal sound. I suppose if I were you, I'd just check it at the ON (motor not running position) from time to time to verify that the sound is not getting worse, and maybe keep monitoring the fuel pressure.
You might want to ask this question on the f150 Engine Forum. There's probably more people with better advice there than you'll find on this new, "specialized" forum.
