fool pumps(things that go woooo in the night)

[Brett Dikeman]

with all this talk of fuel pumps, I got to thinking; I had the back
seat out recently and haven't put it back yet.

I've noticed the same thing I noticed a few years ago, namely, the
pump seems to make a lot of noise when the car's not under load.
Cruising along, I can floor it, or drive uphill etc, and the pump
goes quiet...coasting, foot off the gas, the noise will progressively
get noisier, slowly, but noticeably...maybe over about 10-20
seconds(rough guess.)  From within the car, it makes a woooooooo
noise that occasionally sounds like it's faltering/stumbling(from
outside, just seems to buzz, without faltering, which is odd) at
idle.  The wooooooo noise is what varies with engine load.

Pump is fairly new(2-3 years old) and has buzzed since the day it was
installed.
