The hazard

On certain trucks, the coupling located between the engine fuel supply pump and the air compressor may crack, causing geartrain and/or valve damage to the engine. This could cause the engine to stop running, which can disable the power steering system or stop the supply of air to the air tanks, resulting in insufficient braking power. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will replace the fuel supply pump coupling.
