NHTSA recall 18E081000 · Equipment
Engine and engine cooling › Engine › Diesel
The defect
Cummins Inc. (Cummins) is recalling certain ISX15 diesel engines, part number D103012BX03, and X15 diesel engines, part number D103016BX03. These engines have nylon fuel lines and were built with a banjo bolt containing an integrated single screen filter on the fuel pump. The fuel pump cooling circuit screens may become restricted by debris from filtration material causing the fuel line to burst when the vehicle is operated under certain driving conditions, such as on a long down-hill grade.
The risk
If the fuel line bursts, a significant amount of fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall, increasing the risk of a crash.
The remedy
Cummins will notify owners and dealers will replace the affected nylon line with a steel line, free of charge. The recall began November 21, 2018. Owners may contact Cummins customer service at 1-800-286-6467.
