Any one else having problems with the fuel sender. A friend of mine has a 2006 Z71 and the fuel sender just quit (I guess it couldn't handle the cold). The bad part is, it is part of the fuel pump assembly and the cost is over 300.00. It's a crying shame you have to spend that much to fix the sending unit when the pump is still good. It's been over two years since I got rid of my 2003 Z71 for a 1999 Tahoe. Still have no problems with it, unlike the 2003 bucket of bolts.
