Default Whistling noise from inside tank

My 2021 fxlrs (2 weeks old, 650km) emits a very high pitched noise, I located it coming from around the right front of the tank. If I unscrew the cap while bike is running, it's clearly coming from inside the tank. Suppose it is a fuel pump noise, only there when the bike is running but it pains my ears after a while, after stopping I have a bad case of tinnitus too. Is this a known issue? Something to do about it?

Honestly no man, I can't hear my fuel pump after the initial prime when I flip the switch. I'd take 'er back to the dealer & let them tell you it's normal, then push the issue.

It's the M8 high ptiched whine. I asked same thing, what is that sound.
You are under warranty, you should have no probs.

I've got the exact same sound on my 2021 FXST from the same spot. Plan on mentioning it next time I am in for service as it's obnoxious as hell.

Sure you are not hearing the gear whine of the balance shafts? Especially when the engine is cold.

No it is definitely inside the tank, very obvious with tank cap open. Wife normally doesn’t notice these things, but she also said it’s pretty annoying

After I took my 2020 FXST in for the 1000 mile service it started making the same exact sound you describe. The dealer said if its not affecting anything I should just ride it around and come back if its still happening but Ive been too lazy to deal with their crap. Haven't had any problems but it is pretty loud and annoying. Is there a way to get a recall or something if there are about of people with the same issue?

I hear the same sound as described, 2021 FXFBS. Thinking it's the fuel pump.

Hi all,

I have just got myself a FXST 2021 and I am having same issue with the high pitch sound. When driving at slower speeds it drives me nuts. It’s for sure the fuel pump. Did anybody try and replace the pump with another brand or find any other way to avoid this high pitch sound? Also getting tinnitus after riding due to this.
