The hazard
On certain trucks, the fuel pump may develop a diesel fuel leak as a result of improper assembly process at the factory. Fuel leakage, in the presence of an ignition source, could result in a vehicle fire, causing property damage, personal injury, or death. Correction: Dealers will inspect and, if no seepage or leakage is detected, the fuel pipe fittings will be tightened to specifications. However, should seepage or leakage be discovered, the fuel supply pump would be replaced.
