Customer Question

I have a 2008 2500HD Chevy Duramax Diesel. Recently purchased from dealer with 54,000 miles. It has a 26 gallon fuel tank. I filled at up at 1/2 tank and it only took 6 gallons to top off at full. It seems, actually my gauge telling me that it is only a 12 gallon tank. At a 1/4 tank I fill to full with only 8 gallons. The dealer did a reset and tested the tank to no avail.
Thanks John
