I believe the current recommended procedure is to pull the FP fuse,
start the car, and let it peter out to release the pressure, then
undo various connections, remove old, pour fuel into new filter(I
seem to recall this is to prevent filter from tearing upon FP coming
on and ramming fuel into the filter?) and install?
PS:2 audis in the household, both have buzzing pumps. Neither has
died yet(but both cars are on the 2nd pump, each had it changed very
early in the life of the car, 60k or less.)
