Ok, let me start off by saying I am a first time diesel truck owner... I just ran into a problem today. Low fuel warning light came on. Said 68 miles left until empty on dash. Was running straw through a straw blower on 9 percent grade. Went to accelerate up the hill. And ... Nothing... Engine would only idle. But not rev up. Happened twice today at 1/8th of a tank. Turned truck off back on and was fine both times. So went and got fuel and was fine rest of the day blowing straw. I am guessing but I think I lost fuel pressure due to the low fuel in the tank... Just a guess though. Any thoughts? Never had a problem like this with gas engine. Lesson learned to all diesel rookies. Don't run truck less than a quarter of a tank I guess.
