What yr model 5.9?   03-05 5.9 fuel systems had a tendence to self contaminate causing inj. issues and eventual eng. failure,there was a recall to patch this problem, PM me the full 17 digit VIN ## and I can check it for you to see if and when the recall was done.     
 6.7 don't get the mpg the 5.9 does, the 07-09 had a lot of check eng light problems mostly programing issues. and when it is soccer mom'ed or grampaw'ed daily they get emission carbon build up and will need servicing.
