Intermittent noise from front frunk

[Chsnsurf]

So I have been having this intermittent noise from the front. It seems to only start making the noise when the engine is hot and when the outside ambient temp is hot. When I took the video I had done a short drive in a very leisurely fashion. I do not have the AC on and it was very hot out. I pulled the fuel pump fuse and the sound stopped, but so did the car and so I’m not sure that is what is making the noise. I would think it would be more consistent noise if it was the fuel pump. Any thoughts? https://youtube.com/shorts/WhyzcApEoi0?feature=share

I also think it maybe the fuel pump, and I'm thinking it may be vibrating against the metal skid plate. Hence the noise travel. Good luck.

Thanks Bill. I plan to swap it out this weekend. Hopefully that is all it is. Just seems a little weird it isn’t making the noise all the time. Why only when it is real hot?

It's a mechanical electrical device, as it heats up things change, resistance and load changes and it sounds like that. Before I started my rebuild my pump was doing the same. If you were to get under the car you'd hear it big time.

Thanks David. That makes sense.
