I would like to know where I can find the codes and what each one are that my 8.3 ISC Cummins give to me on a self test. I had a fuel line get a hole in it so I replaced just the fuel line (return to fuel tank) after I replaced it and got the air out of the system it fired right up but I have a check engine yellow light that is illuminated. Could that be that I still have air in my fuel line? I am gong to self test it in the morning but if I get a code I will not know what it means unless somebody can guide me to it. Thanks to all of you for taking the time to post all that you have already posted!
