986 fuel pump sound
 
Hi guys. I noticed a buzz from my front end while I was running the car at a standstill. I suspected the fuel pump so I jumped the relay to fire up the pump and sure enough, there was the buzz. See this video:

fuel pump noise

So I switched out the pump and I'm pretty sure the noise is no different, see video:

replacement pump

At this point I'm open to suggestions, or is this sound normal and I've just never noticed it?!

Cheers guys.

No one able to confirm if this is normal or not? Cheers guys.

Are you sure it’s coming from the fuel pump? The only sound mine makes close to that is the SAI pump when I first start the car but only lasts a short time and goes off.

im pretty sure. I bridged the connection with a 12v after removing the relay for the fuel pump was the only thing running, unless the SAI runs from the same relay but i cant see it. Very buzzy... and im not sure if the new/used pump is any different or if its wishful thinking.
