Fuel Pump Whine

[Theron J. Bliss]

  I tend to find noise is a good indication of fuel pump life 80% of the time.
Id it's making a racquet, it's not a bad idea to be prepared to get a new one,
but you might as well wait for it to quit.  I just replaced mine in my V8Q, and
they completely redesigned the pump, so my dealer price was $325, and the pump
itself is only $140.
