Noisy fuel pump fix
As told to me by my local Audi-trained, multi-quattro owning guru &
mechanic: The Audi service bulletin fix for the noisy fuel pump is to
cut the screen out of the pump intake. He suggests I clean mine with
solvent and clean the gunk out of the bottom of my tank. The gunk is
apparently clogging the screen. This would explain the return of the
noise after replacing the pump and/or filter. Opening the fuel line
allows back flow to clear the screen, but the gunk remains right under
the screened inlet. He also mentioned getting the pump clipped back in
is very difficult, and the whole job would take him about an hour and a
half in his shop. He listened to my pump, quite audible from 50 feet,
and didn't think it needed immediate attention.
