Need help! Weird buzzing sounds!?

So recently my car started making a weird loud buzzing noise from the fuel pump or at least it sounded like it came from there. It wasn’t a constant noise but it continually got worse. I had the fuel filter and pump changed out and it seemed to run better and start up right away no issues. However after driving it the last week the sound is coming back!? Seems to be getting worse too. I’ve attached a video of the condition before the pump was replaced and the sounds aren’t as bad now but still do happen in small spurts. I wonder if the pump wires are touching something causing the sounds? I’m at a loss. I’m going to replace the fuel pump relay just in case that’s part of the reason and add some fuel injector cleaner. Any suggestions? Anybody have this issue? I’ve attached the video link below.

i wonder if your strainer in the fuel tank is clogged up or you have a pinched fuel line?

It seams like the noise is only heard when you turn left. Is it possible that your steering linkage is binding on your fuel line ?

Hmm didn’t think about either but the shop said fuel lines are good when they were troubleshooting. I’m beginning to think that’s possible?

Is the fuel pump vibrating against the housing or the skid plate. Or the bar that goes through there. I can't remember all the bits in there, but I do remember there isn't that much spare room.

That’s possible but the sound happens either way. Right now it’s happening but not as bad just here and there and it’s not dying…yet lol. I did have the turbo tie rods installed awhile back so maybe they moved something in there possibly? I’ll take a look when I get a chance. Thanks!

That’s possible too I’m not sure I just had a new pump installed so it’s possible they didn’t secure it correctly? I will check it out asap. Thank you!

I'm curious what yours is. I tried watching the video but it said unavailable when I clicked. I'm getting a buzzing sound in my carerra but mine is constant and has been there for years. Pretty sure its the pump. Let us know what you find out
