On certain trucks equipped with a Cummins X15 engine, the fuel pump may not have been manufactured properly. As a result, the fuel pump barrels could break and cause a fuel leak. If this happens, the engine could stall.
A sudden loss of engine power could increase the risk of a crash.
Cummins will notify owners by mail and advise you to take your vehicle to a Cummins authorized service facility to replace the fuel pump barrels.
