Please let me know your thoughts I was hoping it might help the HEUI pump last longer as it would not be pulling fuel any longer.
I have a C-9 and it starts great and idles great. How many miles are on it and has the filters been changed plus use only Cat Advanced Efficiency FuelFilters. Sound like you may have injector problems. Do you see any smoke at startup. I use Amsoil 5w40 because of the HEUI pump and only go max 6K before an oil change.
