my wife has a 2001 YUKON, 5.3 engine, about a year ago this same problem started, it has progressively gotten louder. i suspected it was from the fuel pump (have a 1990 f150 & the fuel pump is located in fuel tank & has always made this type noise) but by the time the noise started on the YUKON the warranty was out. i have never heard this noise from any other yukons/tahoes. any ideas or suggestions, since the noise is getting louder, even after filling the fuel tank.
