RE: The Buzzing Bees

["Dan Sinclair" <sinclair@prospro.com>]

Ditto.  Although, mine gets really noisy when it's extremely hot.  On a trip
back from Seattle not long ago, my fuel pump sounded like a loud door buzzer
at the end of the trip, not the usual mild buzz.  My father's 89 80q sounds
the same, and has changed to the agitated buzz after long drives in 100
degree weather as well.  After cooling, the buzz returns to "normal".
Neither have failed after 4 and 2 years respectively, both have new fuel
filters, and both run and drive fine.

Buzzzzz, that's the noise I hear every time i drive around with the stereo
on a
low volume.   My 1988 Audi 80 has had a busy bee in the rear of the car for
atleast three years and no service place, nor any Audi dealer has made a
ruckus
about the fuel pump dying.  Although I have heard the loud humming noise is
a
sign of a sick fuel pump or a fuel filter that has a flipped sock in it??
got
me, (just a shade tree mechanic).  although during the winter months every
Audi
in my family has a distinct humming noise, 200 20V Quattro, 5000s(the
loudest),
100s, A4 1.8T q.  but i have numerous fuel system problems that have been
fixed, so the buzzing could be causing all these problems, but who nose?
