Buzzing noise after fuel pump recall?

[Ratbert]

Is anyone else experiencing a buzzing noise from the engine compartment after having the fuel pump recall done? It's very noticeable after turning off the engine. No clue (yet) how long it continues or where it seems to be coming from.

Probably unrelated, but I also had the IBS on the battery replaced to resolve my start / stop warnings. That was one of the "get this resolved before my warranty expires" tasks.

Interesting. For some reason it never did it with the old pump.

It did. It's probably just louder now than it was before.

Maybe? I never noticed it before. Now it's just about obnoxious.

I have one with the recall completed- it is annoyingly loud for about a minute after shutoff. I bought it new with the recall completed though, so not sure what the prior pump noise was like.

That's pretty wierd I have 4 and my son has 1 ecodiesel they've all done it since new and all done it since the pump has been replaced also I also have a 2020 longhorn 1500 ecodiesel and it's never done before or after the replacement of the pump

Pretty bizarre. Maybe my old one was defective or stupidly quiet.
