I can really hear my fuel pump/sending unit. Is that good normal or bad?

It’s a chevy thing

I just changed my fuel filters today and my fuel pump is very loud. Even after driving down the street and cycling the motor on and off 3 or 4 times.
Im guessing its running at full capacity for a period of time to get out any air in the line caused by the fuel filter change.

Can anyone comment on this?

I think mine ran kind of loud for a while and then quieted down. Not sure why it does it and I don’t remember how long it took either.

Is it cold out by chance? That could be part of the problem I suppose.

Mine is the same way when it is cold (like 30s F out) and after a filter change. It quieted down after a couple of outings.
