Yes.

The louder the buzz gets, the closer the pump is to failing. I ignored
mine for a little too long, and got to pay a $50 towing bill in addition
to the $250 pump replacement. Also, if the pump fails, you'll have to
drain the fuel line and replace the first filter, too, as bits of pump
can get into it.

Replace it on your schedule, it's easier.
