I can now pull my tt, cattle trailer or hay trailer as fast or hard as my diesel reserves allow.

My question for you: My 2004 has the same problems as mentioned on orignial post. This is all a pain for sure but what happens if you just put up with it and let the whinning continue? Is there damage that can happen? Mine seemed to start after three years old and the fuel changed. I lost power along with the whinning but when I used the cetene boost the whinning continued but the power hung in there. Per his question above, what was the cost to change out the systems? thanks
