Blowing over the top of a Coke bottle sound

My car has developed this noise more frequently now.
I know it has been discussed here many times.

I did a search but cannot come up with any thread that talks about this issue.

Please help.

Annoying woo woo sound right?
Mine has been doing this for a couple of years, mainly at steady rpm driving.
First place to look is the fuel filler vent valve, one of which I (finally) bought.
There’s a DIY on the Pelican Parts site on how to swap this out.

Had this sound some years ago, replacing the valves did not solve it. My fix was to put a piece of sponge in the hole in front of fuel filler cap.
Still allows for ventilation but will stop the sound

Man you guys must have some quite cars to be able to hear this sound coming from the fuel filler door area.

I placed a rag around the filler nozzle to see if it blocked this damn noise.

It worked.

Now at least I know where the noise is coming from

Use duct tape to cover the vent hole to verify.
