The fuel pump in the '90 has become audible during normal operation.
Previously, the only time that I could hear it was at the first turn
of the ignition key, when it got power there would be a small hum.
Now it's got more treble sounds, not quite whiny.

Something I can ignore for awhile or something that I should replace
right away?
