Its been quite the issue here in Montana. Lots of guys pulling a lot of weight. I have two more coming in later this week for the same issue. I wish we could just reprogram these things and change the tolerances-no can do.
We recommend fuel filters every year or every 15,000 miles. That sure seems to help with many of the fuel issues on these trucks. I have seen collapsed fuel lines ONE time.
I'd recommend starting with the filter, and then spraying off that cooler. Though come to think of it, I have a gentleman that has a Duramax that we actually pulled/measured fuel return and it was high on 3/4 injectors on one side. That pretty much confirmed the issue was related to injectors on that pickup. Its a pain of a test, but worthwhile.
Hollar at me if you need assistance with bulletins, etc.
