2013 Chevrolet Silverado 2500

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.
