Cp3 to change or not to change
My 2003 cummins has 320,000 miles on the CP3, I am changing the fuel injectors and wondering if I should change the CP3 at the same time, not sure what the life expectancy of these pumps are, mine has always been fed with the fass fuel system and new filters any idea how long these pumps last,
