i forgot to add, you may want to check the accumulator, inside there are 2 porcelian pins and it is very common for them to break, that what happened to mine, if that happened there will be tiny white pieces everywhere so be sure to blow out all fuel lines so they are clean, and on the fuel sensor switch, there is an update, if the wiring hookup is a rectangular shape, you will need a adapter to make a new pump work and Cummins does not have enough brains to put it with the new pump so you need to order it from them and wait another 4 days or do what I did cut off the stupid end and use butt connectors and hook them up but be sure to mark each one before cutting because one end has numbers and other has letters, good luck.
