Anyone find that the fuel pump starts to whine when using a Napa fuel filter compared to a Volvo or Sierra on an 03 gxi. 5.0?

NAPA is WIX and have never had an issue with the filters. That said, I don't use Sierra

Is it not just the HP fuel pump kicking in at certain revs and demand ? Trade mark of the MPI and GXI. Mine is much more prominent when the hood cover Bimini type thing is up. Amplifies any sound. Idle air control valve can whine or whistle too at lower rpm.
