re: Noisy Fuel Pump

I replaced the pump in my 87 5kCSTQ a couple of months ago at 115k miles.  
It had been noisy (whiney buzzing sound) for more than a year, but did it 
pretty much all of the time. Don't remember it getting worse in the winter. 
 I finally decided to change it when people would turn and stare at the car 
when I drove by.  Now all is blessed silence.

I did have occasions when the pump would suddenly start making a very loud 
noise, and the fuel volume to the engine dropped noticeably, causing it to 
stumble.  It would stop and return to the regular whine/buzz when I turned 
the ignition off and then back on.

For what it's worth.
