I have a 2011 6.7 with 110,000 miles on it. 30,000 on a new fuel pump. I replaced it because I broke off a fitting draining the fuel tank after contaminated fuel (the contaminated fuel never went through the pump or engine, I caught it before running the motor).
Your posts have me worried. I have never knew of this issue and have recently had a new, louder noise of the truck's fuel pump (after the truck turns off) that is louder and more growly or varied pitch grown.
Do you guys think this might be a fuel pump? They are easy to change. If I do change it, just buy another 2011 or does the new 2016 just bolt on without mods.
I have never used fuel lubricant only some additives when the winter fuel gels up.
