1989 V12. Interesting…2 weeks ago, vibration which stopped around fuel pump… Today was a warm day here in Syracuse, removed casing, pulled up fuel pump, surround rubber came out of metal collar. Started car up and heard buzzing sound and traced it back to the fuel pump. Would resetting the foam back around the pump and putting it back in the metal collar extinguish the noise? Hate to fool round with gas prevalent. Wiggling pump seems to alter the bussing but does not stop it.
Thanks!
There are no stupid questions but obviously placing the pump back into its mount would help a lot. They always buzz, it’s mostly a motor with a little roller vane pump, cavitation or trapped air not impossible.

All fuel pumps buzz. You can hear in trunk.
If you can hear it from inside cabin, then something is wrong.
The rubber sock and brace isolate the humming/vibration, they are necessary.
If you can still hear humming from cabin, then pump must be touching floor of trunk, fix brace position.
If still hear humming, then pump is bad, or the pump is not getting sufficient fuel delivery from sump tank.

your fuel hose says 88 on it? If your fuel hoses in the trunk are original, you’re living on borrowed time.
Well, looks to me like “the cats out of the bag”
