Hazard description
On certain trucks, the fuel tank's longitudinal seams may have been fabricated using an incorrect weld speed for the given material thickness. This error resulted in a weld which did not completely penetrate the entire material thickness. Fuel tanks possessing this defect could leak diesel fuel in the event of a vehicle crash. A fuel leak, in the presence of an ignition source, could result in a fire. Correction: Dealers will inspect and replace any defective fuel tank.
