IMO..... cummins motor, the interior and ride of the chevy and the looks of a ford.Ford screwed up by getting rid of the 7.3. Loved that motor for years!!! But my duramax now I can't complain about anything but fuel mileage. 13 mpg city and 15 hwy. Not good!
Sixtynhalf Did you do the lift pump upgrade and put it in the tank? On the 03 many had an exterior lift pump that when it goes out puts strain on your injector pump and normally causes it to fail. That normally happens on a long drive where the lift pump provides enough initial pressure to start then fails. The injector pump is still able to draw fuel from the tank however it creates lots of stress on the pump... Most aftermarket pumps are not in the tank... Not sure why.... Many lift pumps fail from dry suction when prime is lost for whatever reason. I put a factory in tank pump kit in that dropps in. the in tanks don't lose prime and always stay lubed. it is also the design that they use int the 04-06? lift pumps are cheep $200. common rail injection pumps are not $2-3k When my lift pump whent out i lucked out it was a short trip, 5 miles, and it failed during that trip. Normally i run my truck for 200+ miles without shutting it off...

So what's the story on getting such good gas mileage out of your diesels?
