fuel pump/sender unit

[jocko]

good evening folks - quick question. Have had a few codes for my sending unit accompanied by an occasional fuel gauge dropping to zero. know i need to change the pump/sender assy in the tank, but would rather hold off a bit for now. I've got just shy of 150k mi on my '01 Z71. As long as the pump is good, I can live with the fuel gauge issue for now. It actually stopped dropping to zero anyway now - just reads a little high, again, can live with that.

Anyway, moving cross country in a month and wondering 2 things -

1. Has an iffy sending unit immediately preceded a total pump failure for anyone? I don't think their functions are linked, even though they are replaced as an assembly, but curious.

2. About how many miles have you all gotten on your fuel pumps before they failed? I have no indications of a bad pump - just the fuel gauge issue.

Thanks for the help!
