Kenworth in certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
The short version
PACCAR Incorporated reported a problem with the engine diesel. Here is what owners need to know.
In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.
Cummins will notify owners, and dealers will replace the suspect fuel pump cooling circuit screen, free of charge.
