does it belongs to fuel pump vacuum sound issue, i have already posted the issue....

**I have alto 660 2019 model, but i never faced such issue as its almost more the two year but from last month i am facing this vacuum sound issue in my alto specially when i refill my fuel tank, but sound didn't come continues.
kabhi awaz achanak ajati hai for few seconds kabhi 10 mins tak ati rehti hia and automatically band hojati, i doesn't seem normal as i have other efi car but i never hear such sound coming from fuel pump.
does anyone know how to resolve this issue or the only solution is to replace the fuel pump?
anyone suzuki dealership or paksuzuki motors please share your views.**
