That code would be for the line from the tank to the pump! 4357 was for the line to the def injector! When the 1st line fails you should change both cause it gonna fail sooner or later! The new lines should be updated and rarely give trouble! These def system are pretty simple and usually don’t take long to diagnose a problem!
