General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.

The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank – it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.

GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

General Motors LLC (GM) is recalling certain model year 2012-2013 Chevrolet Silverado HD and GMC Sierra HD vehicles, equipped with 6.6L diesel engines and dual fuel tanks.

Owners may contact Chevrolet at 1-800-222-1020 and GMC at 1-800-462-8782. GM's number for this recall is 13420.

        Did the wheels on this truck come off a Hinda Civic? They sure look tiny.

      Lol, like GM truck gauges have worked at all in the last 10 years. At least they recalled them on the pickups and fixed our Sierra under recall. They never gave jack to the SUV owners whose speedometers, tach, temp, oil pressure gauges all failed. Frankly GM just makes a shoddy product, is a poorly run company and screws its customers. I would buy anything but a GM.

      Back in the old days you would have a dash switch to switch between the main and reserve tank. That system worked perfectly fine. Why fix something that's not broken?

      I've heard a few different people comment how the fuel gauge on their chevy truck will stay at 3/4 full for a long time, and then rapidly drop down to near empty, or do other weird things like never go back all the way to full. It's been a few years since I've heard any of that though. Definitely pre-2012 trucks. Was there ever a recall for those?

        Not sure if it is the same issue, but they had a similar problem with the GMT800 trucks about 10 years ago. The fuel lever sender is an arc shaped rheostat at the end of the fuel pump's float arm. The little contact pad would corrode and the little contact fingers would hang on the deposits. It was from dissimilar metals or the wrong grade of metal selected by some third world tier 5 supplier or something. Never recalled it to my knowledge, but it was a pretty widespread issue for vehicles with 2-3+ years on the road. My old Cavalier would do the same thing at about 1/4 tank. Got stranded a few times. Same fuel pump supplier (Delphi).

      Hate to tell them but I have a 2013 1500 Silverado (gas) that the gauge and the computer are off by up to 2 gallons. All most left me on the side off the road. Told the dealer and he said it could not be fixed.
