I own a 06 Sierra 5.3 SLT. I have ran out of gas twice now with the gauge showing 1/4 tank left.(Gas can -Dont leave home w/o it now);) I have been researching everything thing that I could find from using Techron Plus to the GM fuel cleaner to just replacing the fuel level sensor at about 100.00 or so. My truck has 54000 miles and the pump at 450.00 on the web. I think the pump is still in good shape. As I stated the gauge shows 1/4 tank still left but empty -no erratic bouncing from full to empty which leads me to believe the float is the the problem! I'm by no means a mechanic so any help on this problem would be greatly appreciated. Would it be smart to just replace just the level sensor or the whole assembly pump and all? Thanks.
 
Have you checked with a GM dealer before spending money on something that may or may not fix the problem.

Sometimes these things can be corrected with a updated computer flash..

Btw - The GM fuel system cleaner is Techron but stronger that some of what you buy at the discount store.
 
Talked Gm dealer today said they could fix the problem 400-600. Told me I could tell the kids Santa needed some work done for XMAS! So I guess I'll have a gas can on my sled till after xmas this year.
