Do you hear any noise from your fuel pump beyond the normal tip in rattle? For example, while accelerating?

I used to before PMM and that was with DP and TP. Makes noise at tip in and when lightly accelerating. Most likely makes noise WOT too but I couldnt hear it. Now I cant hear it at all unless I really try to. When it gets colder it gets louder.

Based on your video your car sounds exactly like mine. However I do have aftermarket internals which tend to be a little louder than stock pump.

Mine sounds exactly the same...however mine didn't start making that noise till after I installed my AT internals. Car has like 5K or more miles on the AT internals now. It's just the noisy fuel pump.
