2006 Chevy diesel truck fuel gauge

[davek]

When the fuel gauge on my 2006 Chevy diesel shows empty only about 14 gallons ar eneeded to fill it. Not much of an issue since I've only been using it around town, but now I have to make several long drives in it next month and I'd like to have an accurate readout of my fuel state. Any suggestions about how to go about fixing this (or getting it fixed in the Tulsa area) ? I'm not the original owner, I hate to think there might be something taking up room in the fuel tank.

some Columbian Bam Bam perhaps?

Carry a gas can.
My auto mechanic buddy said Chevys (and Toyotas) are notorious for this.
my suggestion is to figure your mpg and calculate wen to get gas.
I've ran my Prius out with 3 bars(just under 1/2 tank, over 1/4)) on the gas guage.

I found the Duramax forum and apparently this is a common problem. I'll carry a can and fuel every 250 miles or so.
