What should the temp be on a Cummins 400?
It was typical of the temp gauge going to 220 degrees and my MMDC’s LCD display would flash the high temperature warning and sound the alarm. But, 220 degrees isn’t the danger point. It’s a warning that you are getting there soon though. What I then did was manually downshift the Allison to keep the revs up.

Where is the fuel hose on a Cummins 400?
Cummins changed the design in 2006 to where the hose coming right off the block is right next to the Turbo. They welded a piece of pipe coming off the engine block to re-route the hose and I have now had no more problems. Additionally, FYI, another Cummins campaign item is the fuel hose to the fuel rail on the pressure side.
