Why is my Cummins ISX intermittent shut down issue?
That is a common problem with them leaking. They will only leak when they are running. After they shut off and the engine is running the main fuel pump will suck fuel past this pump. If the electric pumps leaks out fuel when it is on, then it will allow air to get sucked in once it shuts off. Thanks for all of the advice.
