fuel pump high pitch sound?

[Saftie]

I recently started to notice a high pitch sound/humming coming from my fuel pump while bike is running.
Never noticed before. I assume this is not normal?
Any ideas what it could be?

Chaffed wires probably. Mines been doing the same for almost a year now. It hasn't really bothered me to the point of fixing it yet though

Thanks. Dont think so. I just had the pump out a few weeks ago and fixed one chaffed wire, replaced the low fuel sensor and wrapped all other wires with heat shrink. I am pretty sure I am good there.
If yours is still running after a year, I guess I dont need to worry about it too much for now
