Do in-tank fuel pumps give any warning of impending failure/

As a rule that I use, based on a GM mechanics advice, I replace the pumps at 100,000 miles, and use only GM/Delco brand. They can be had for $120 and only take a couple of hours to change on a P/U truck -remove 6 bolts, unplug wire harness, slide bed back 3' and replace.
