Message I am running a TT fuel pump in a NA. Since its a TT fuel pump running at 12v its very noisy on acceleration/cruise due to the NA FPCU only running low/high.

Today I noticed with my fuel tank reading below a quarter tank, the loud buzzing noise isn't there. It makes me wonder if in my case i am not hearing fuel pump noise but something else?
